  • Half Cousins galore!

    Half Cousins galore!

    This month has actually been pretty active for DNA cousins, I had one of my cousins pop up, they are actually my half 1st cousin but in my family we don’t really use “half”. I also had the child of one of my cousins pop up, again they are half relation but we don’t use those terms.

    Itr is actually interesting to see the shared relatives between both of my cousins. I was expecting to see just relatives of my grandfather but sprinkled in there were relatives from my grandmother’s side and my father’s paternal and maternal side!

    This is interesting to me because my grandparents were from different countries. My paternal grandfather was from Saint-Barthélemy in the French caribbean, my paternal grandmother was from St. Thomas, US Virgin Islands and my maternal grandparents were from Dominica.

    I’m trying not to get ahead of myself while speculating on the relationships of all these dna relatives and what it means that they show up in my shared relatives in common with my cousins. It is entirely possible that I am related to this person on their paternal side and my cousin is related to them via their maternal side. I have no idea how I’m actually going to prove these lines though, Dominica genealogy is the most frustrating one I have ever had to deal with, if I could find my way to a family history center and view the records on, FamilySearch I would be so happy but I have no way to gain access to one. I hope that the records for Saint George parish will be made available one day and I’m able to search whenever I want.

    Here is my Half first cousin, their parent is my mother’s half sibling. We share 7% of our DNA, 485 cM across 22 segments. My cousin and our aunt who is my full aunt share 1031 cM across 34 segments while I share 1808 cM across 60 segments. My cousin actually share a little more DNA with my brother than I do and I don’t like it lol, my brother actually shares 594 cM across 20 segments, it doesn’t really change the fact that this is our cousin but in my mind it’s like they are more his cousin than mine and it makes me a little sad. It’s an illogical thought but my mind travels down these paths frequently.

    Now, here is my half 1st cousin once removed, we share 4% of our DNA, 301 cM across 11 segments, their shared DNA with my aunt is intereting, 223 cM across 10 segments, I share more DNA with them than they share with my aunt, I wonder if it means that my mother shares more DNA in common with this half sibling or maybe their other parent is somehow related to me through my father. This cousin’s parent is my half 1st cousin which means their grandparent is my mother’s half sibling.

    So here is a little chart showing piece of my family tree, I have way more aunts and uncles than is shown here, I just wanted to show where my cousins are located in the family tree.

    I wish some of my cousins on my father’s side would test so I can see how much DNa we share and what relatives they might be related to that doesn’t show up for me or my brother. They don’t seem to be interested in it but one can only hope.

  • Ancestry Pro Tools

    Ancestry Pro Tools

    Ancestry has really been on my last nerves for a while now. They did an update a while back where you can’t view your DNA relatives in common with someone or view their tree unless you have an active subscription, and I find that move left a sour taste in my mouth. Even without a subscription, I could separate my DNA relatives into groups to figure out how they are related to me. But it gets even worse – groups, even my custom groups that I had created over many years, are now paywalled. I swore that I wouldn’t pay for Pro Tools, swore that I would not pay for another subscription, but Ancestry kept enticing me with $1 subscriptions, and I cave every single time.

    In June, I decided that I would take the bullet and pay for Pro Tools. I parted with my €11.25 very reluctantly. Oh, I was punching the air and saying if it wasn’t worth it, I would be so mad. I’m even more pissed off that it has proved very useful. The one feature that I bought this subscription for was the Advanced matching. Basically, it does what 23andme and MyHeritage both do; it shows you the cM your DNA match shares with your matches in common and how they are possibly related to those matches. Angry, I am so angry because it immediately proved that my theory about a half-second cousin was correct. I had guessed at the connection to our shared DNA matches, but I really did not know how much DNA she would share with our shared matches, and now I know.

    I actually wrote a post about this match and how I went about proving that she was a half-second cousin. I just have the information about how much DNA she shares with my known half-second cousin 2x removed.

    Here’s the post if you haven’t read it: Detective Lynnette and the Case of the Mysterious DNA Relative

    I want to say I don’t know if I will renew, but I am still undecided because I have not done everything I wished I could do with this new tool, and I will no doubt continue to get more DNA relatives and I’ll need to figure out how they are related to my other matches. I will probably stagger my subscription because I cannot pay for this every single month.

  • Ancestry Updated Caribbean Communities

    Ancestry has released an update for their Communities in the Caribbean.

    I received an email telling me that I had two new Communities.

    As we add people to our database and keep developing the science behind AncestryDNAⓇ, we’re able to continue adding new communities to provide more insight into your family story.

    With more communities from African American Communities and Afro- Caribbean Communities, you could uncover new connections between your family story and other parts of the world.

    Email from Ancestry

    I couldn’t really tell you what they added because I haven’t been keeping an eye on the different communities just the two I had. They did remove the Afro-Bahamians and Afro-Bermudians which didn’t apply to my family history.

    I really didn’t notice what was updated at first but then I realized, they added Dominica.

    I was curious so I went through the feature where you can compare Communities with your DNA Relatives and saw that they also added Virgin Islands but I didn’t receive it. Which makes no sense to me as my father and his maternal line is from the Virgin Islands and has been for generations. I myself was born in the Virgin Islands and most of my DNA Relatives are from the Virgin Islands and have family still there.

    It is very similar to 23andme not assigning Saint Barthélémy to either my father, myself or our many cousins with ties to St. Barts.

    I guess all I can do is wait for their next update and see if either my brother or myself gets assigned to the Virgin Islands Community.

  • Detective Lynnette and the Case of the Mysterious DNA Relative

    Detective Lynnette and the Case of the Mysterious DNA Relative

    Let me tell you about this Mysterious DNA relative in my brother’s Ancestry list that haunted me for a few years.

    Mystery DNA Relative

    Shared DNA: 66 cM across 6 segments

    Unweighted shared DNA: 73 cM

    Longest segment: 28 cM

    This was a fairly close relative but she did not match with any of our other relatives, no matches with the hundreds of relatives on our grandfather’s side so I could cross that side out. No matches with our maternal matches so she wasn’t related to our mother. No matches with our father’s maternal grandmother’s relatives so that only left Alfredo who I wasn’t sure was our real great-grandfather because of the lack of DNA matches.

    The tree was no help because everyone up to grandparents was Private so I had no clues to go by but this was a mystery I was determined to solve.

    By chance, I happened to see this same relative on MyHeritage with a more open tree, and going through the tree I immediately noticed that her maternal grandparents were not from the Virgin Islands and I did not recognize any of the names. I started working on a mirror tree and everyone was born in the USA so I crossed out her mother’s family as being the connection, her father was Private but his father was not, it was just a name but one I know from the Virgin Islands.

    I was intrigued.

    I knew the last name but not the first name so off to Familysearch and Ancestry to do some searches, I was coming up empty, even looking through my DNA relatives I didn’t get any other matches with this surname in their tree, what could this possibly mean?

    It was scratching at the back of my mind but I didn’t want to answer it just yet, I wanted solid proof and that came a few months after I did my own DNA test at Ancestry, this match still was the only person connecting to both me and my brother until she matched with one other person.

    The New Match

    Shared DNA: 98 cM across 5 segments

    Unweighted shared DNA: 98 cM

    Longest segment: 38 cM

    This new match had a surname I knew but couldn’t place, she was instrumental in me finally connecting the mystery match to the tree and our family but the name was aggravating me with its illusive trail until I went back over my tree looking at the children of my great-grandfather Alfredo. There it was the name that was flirting with me, my great-aunt, the half-sister of my grandmother had married a man with the name of the new match. The new match was the granddaughter of my great-aunt.

    So if the mystery match also matches the granddaughter of my great-aunt that can only mean one thing, she was also a descendant of my great-grandfather Alfredo, but how? The last name of her grandfather, her grandfather was the full sibling of my great-aunt, they shared the same mother instead of being half-siblings like they were raised. So her grandfather was my great-uncle and that made her my half-second cousin.

    I honestly wondered if I should have even attached her grandfather to Alfredo but it seemed to me that maybe she was searching for her relatives, nobody takes a DNA test and uploads to multiple sites just for the fun of it. Oh yes, I forgot to mention I also found her on Gedmatch. So I put the information in my tree with the DNA connection and hoped she would see it and it would help.

    I have to admit though, Alfredo’s parents are still giant mysteries to me and I am no closer to cracking that particular nut just yet. I’m hopeful but the matches on that line are very few and far in between. At present count, I have just 3 matches excluding my brother. The two in this post and the granddaughter of Alfredo’s half-brother. With so many half connections is it any wonder that the DNA connections are on the smaller side?

  • Is knowing your Maternal Haplogroup helpful?

    It depends.

    In my father’s case, because he was adopted and we don’t know much about his family, matches on the X are pretty helpful for me.

    In my case they aren’t very useful because I have two Xs and any match on my X will need thorough research to figure out which side of the family this match comes from. I inherited an intact X from my father which is a recombination of his mother’s mother and her father. I also got a recombined X from my mother. Let’s take a little look into what this will look like in terms of DNA relatives.

    Matching with my father.

    As you can see, I share 50% DNA with my father including the X.

    We have different Maternal Haplogroups.

    Even though we share an X we don’t have the same Maternal Haplogroups because it is inherited strictly from the mother. My Maternal Haplogroup is L1b which came from my mother, her mother, her mother, and so forth. My father’s Maternal Haplogroup came from his mother.

    Matching with my maternal aunt.

    This match is my maternal aunt and as you can see I share 25% DNA with her including an X, in case you didn’t notice it’s not an intact X because I inherited DNA that my aunt didn’t.

    Sharing the same Maternal Haplogroup.

    Because this is my maternal aunt, the fact that we share the same Maternal Haplogroup tells me that she shares the same mother as my mother. I can also look at the number of cMs we share and 25% indicates a full aunt meaning she shares both parents with my mother.

    Matching with my mother’s first cousin.

    Here’s my match with my mother’s first cousin, we don’t share an X because he inherited his X from his mother and I’m not related to his mother. This tells me that I’m related through his father who was the brother of my grandmother.

    We don’t share the same Maternal Haplogroup.

    The interesting thing about this cousin is the amount of DNA we share. I thought I had just inherited more DNA from my grandmother than I thought but I recently learned that my grandparents were possibly related. I have not found any actual evidence that this is true but like most Islands Dominica is small and it shouldn’t surprise me that there could be some endogamy going on.

    I hope this was helpful in understanding how Maternal Haplogroups can help you in your genealogy research.

  • New Ancestry DNA update plus SideView

    I literally just received my Ancestry results and already they have been updated. If you hadn’t read my post talking about my Ancestry DNA results you can find them here My Ancestry DNA Results!

    Now let’s get into my new percentages and whatnot, but first what is Ancestry SideView?

    Ancestry SideView is simply Ancestry trying to tell you what DNA you inherited and which parent it came from, contrary to what people may have you think it is not the first of its kind, 23andme has done something for quite a while, you can find it in you Parental Inheritance Report and I’ve shared mine in a post before which you can read here Phasing My 23andme With My Father. As far as I can see the only difference is that with SideView you don’t need any parents to test but to me, it seems that might lead to some inaccuracies because I can’t fathom how they can pinpoint from which parent you inherited which gene if neither parent tested. I know this might seem to be biased because I have said again and again that I prefer 23andme to Ancestry but it just doesn’t seem logical to me, I am open to the fact that I might be wrong though.

    Here’s my Ancestry SideView, it really doesn’t seem all that accurate to me, just going off of what I got on 23andme where I am phased with my father, according to 23andme I inherited no French from my mother but Ancestry says I inherited 2%. Someone must be wrong and I’m leaning towards Ancestry being wrong just because my father is there to compare my results with.

    Now here’s my 23andme Parental Inheritance Report. The number here makes perfect sense when compared to my paper trail, I don’t really see how Ancestry arrived at the percentages they did.

    Before I forget here’s my update results from Ancestry. A bit of a shakeup, Nigeria decreased while Benin & Togo increased, Spain is completely gone or they changed it to Basque, Mali decreased, Ivory Coast & Ghane is increased, France increased, England & Northwestern Europe has decreased, I gained Senegal and most of the other changes are minor.

    Here are my results in comparison to my brother’s results, his France is still pretty tiny but it might just boil down to him not inheriting those specific genes.

    Ancestry has a lot of work to do if it wants to impress me, maybe including a chromosome browser or showing me how my DNA relatives are related to each other? 23andme has truly spoiled other tests for me.

  • My Ancestry DNA Results!

    On March 5 I finally sent in my Ancestry DNA kit and anxiously waited on the results. So many things went through my head, but my biggest concern was “what if it failed?”.

    A valid concern since my 23andme test failed the first time, my fears were unfounded this time as my DNA Results were finalized on the 30th.

    It was weird looking at it because I was so used to my 23andme results and looking at my brother’s ancestry results, my own made zero sense to me.

    Lyly’s Ancestry DNA Results

    As a refresher here are my 23andme Results. After going through this process I still prefer 23andme over Ancestry. The only thing Ancestry really has going for it is the family tree attached to it but I’ve gone through all of this before in my post The Reasons why I prefer 23andme over Ancestry DNA.

    Lyly’s 23andme Results

    It’s really interesting watching my results compared to my brother, the differences in the genes we inherited are not only fascinating but it has helped me to verify some lines in our family tree. I have a few DNA relatives that he doesn’t have and they were the links I needed.

    Comparing my results to my brother’s results.

    The first line that I was able to confirm was my Grandfather’s paternal line, my brother had 0 matches from that line and it made me very curious, was it that nobody tested, or were there more nefarious reasons? Were we not actually LaPlace’s? I was going through the Thrulines and saw that I had two matches when I was expecting one. My brother is the match I was expecting and the second match was the Great-grandson of my Great-grandaunt, this person is my 3rd cousin and I have never heard of them, I knew that my Great-grandaunt had married into the Olive family and my Grandfather traveled to the US Virgin Islands to stay with her but my 3rd cousin’s last name I’ve never seen mentioned anywhere before.

    The second line I had confirmed was my Grandmother’s paternal line, same as above I was questioning why there were 0 relatives in my brother’s DNA relatives but it turns out he just didn’t inherit those genes while I did. I matched with the granddaughter of my Great-grandfather’s half-brother which makes her my Half 2nd cousin 1x removed, the DNA we share is also on the small side with only a 14% chance of being a Half 2nd cousin 1x removed but given the fickle nature of DNA inheritance, I’m just lucky to have even inherited any DNA from my 2nd Great-grandmother Sarah.

    Right now my focus is to see if hidden within my DNA relatives or even in my brother’s relatives there is a clue to who the father of our 2nd Great-grandmother Maud is. I am almost certain that it will be linked to the three relatives with the surname Hynes.

  • Breaking a 16-year brick wall – George Petersen

    My Great Grandmother on my father’s maternal side was Valderia Eugenie Petersen, she was the daughter of Maud Hines and George Petersen.

    I know a lot about Val’s mother and her mother’s maternal family but her father was a mystery because all I had was his name.

    The only reason I even knew his name was because of the index for Valderia’s Social Security Application.

    It has taken me 16 years to finally find his family, with the help of DNA relatives on Ancestry and knowing more about genealogy now than I did when I was 19, I was able to build a family tree of only men with the name George Petersen born between 1870 and 1905. I choose those dates because I knew Valderia was born in 1920 and her father could have been anywhere between the ages of 50 and 15. I have seen very young parents in my searches so 15 is not common but not unheard of.

    I’m getting a little ahead of myself so let me backtrack a bit, before I even began my George Petersen tree I identified DNA relatives from my father’s maternal side of the family and those who were not related to Val’s mother’s side I separated and focused on building branches for them in my own tree with the hopes that I would find the connection but the higher I got on their trees the more I didn’t recognize the names. It was also more difficult because some of them didn’t have any shared connections! They were puzzles that intrigued me. I could see that they were related to each other somehow but my brother just didn’t have the same shared DNA with each of them.

    This is when I got the idea to look for all the George Petersens, and there were so many of them that I just started labeling them I, II, all the way up to XIII. George Petersen XIII (13) was the one!

    His full name was George Henry Petersen born on June 26, 1879, to George Henry Petersen and Lydia Gasper. Gasper also spelled as Jasper and Yasper is a name I’ve seen in my DNA relatives’ trees and I got that lightbulb feeling that this had to be him, he never showed up in any of their trees but his grandmother on his mother’s side was the half-sibling of my brother’s DNA relatives’ 3rd Great grandfather, 4th Great grandfather, and through another side, his mother was the sister of these relatives Great grandmother.

    St. Croix, Danish West Indies, Denmark, Records of Enslaved and Free People, 1779-1921 for George Henry Petersen

    When I entered his information into my tree and attached him as Valderia’s father, I had to wait the next day to check the Thrulines to see if it would show me anything interesting and it did.

    I found 3 other DNA relatives, one of them was only 7cM which I didn’t really pay any attention to because of how small it was and they literally shared no common matches so I had no idea they belonged on my grandmother’s side but it makes me feel good because this meant that I had found the right person.

    Days like these show me why I love Genealogy and pairing DNA testing with it. Conventional Geneaology can only get you so far it’s the DNA that will help you break those decade-long brick walls.

    My focus now will be to find the father of my 2nd great-grandmother, Maude Hines. I know that he has to be a Hynes from St. Croix because I have DNA relatives with the Hynes last name and they share common relatives from my grandmother’s family but they do not match with my grandmother’s father or her most of her maternal side. There’s some overlap which isn’t surprising with the size of the Island but the connection is there and it’s waiting for me, I just have to find it.

  • 23andMe – New African Groups Added to Ancestry Composition

    I know I am late to talk about this but that’s because I’ve been waiting to see if they were doing staggered updates. It seems that everyone who was going to receive this update already received it.

    If you have no idea what I’m talking about back in January 23andMe added new Ethnolinguistic Groups to their Ancestry Composition, basically they were able to narrow down where in Africa your ancestors might have come from based on the number of Africans you matched with. This is very important to the African diaspora because the majority of us have no idea where our ancestors came from.

    The Groups added include Fula & Wolof, Mandinka, Temne & Limba, Mende, Yoruba, Igbo, and so many more, you can read the full blog post from 23andMe here.

    When I saw someone post their updated results on Reddit I immediately went to 23andMe to check both my father and my accounts. My father’s results were the first I saw, I was hoping to see where in Ghana our family came from but he did not receive a match for there even though it is his largest percentage. Instead, he received a match for the Yoruba people.

    My Father’s Nigerian update

    I clicked over to my account but I didn’t seem to have any matches. I assumed they were rolling out the update to newer accounts first but it’s been a month later and I still have no update. I honestly don’t know how they match the profiles because my father has only one full African DNA relative and he is from Angola, not Nigeria. On the other hand, I have three Nigerian and one Ghanaian DNA relative with direct ancestry from Africa.

    No updates for me

    Interestingly enough, one of my aunts did 23andMe and her results came in just as they released the new groups. She is my maternal aunt and received two groups. Igbo and Yoruba. She’s also mostly African with a small bit of European which further cements the idea that we had Indigenous DNA from my maternal grandmother a tall tale. All my life I’ve been told we had Kalinago ancestry and the fact that there are Kalingao people in Dominica made it seem not unlikely, why would my mother, grandmother lie about such a thing, when I showed my results after phasing with my father my mother told me that one of my aunts said it wasn’t Kalinago but some other Asian, this can’t be true either since it would have shown up in my results, my aunts results, or even my mother and aunt’s first cousin. Both my aunt and their full first cousin show no trace of Indigenous or Asian DNA. So what’s the truth? The truth is more than likely a biracial child they tried to pass off as Asian.

    Aunt Nigerian groups
    Comparing my aunt (left) with her full first cousin (right)

    I honestly thought my mother’s maternal first cousin would help separate the DNA relatives and he has in a way but like all small Islands, there are overlaps so I’m still stuck trying to figure out how some of these people are related. All I can do at this point is hope that someone who knows more than I do is willing to share what they know.

  • From Africa to the Caribbean: Links To Our Past

    From Africa to the Caribbean: Links To Our Past

    In June my father received a request to share DNA and this isn’t anything new or special because some people do request to share so they can compare their results with yours, I’ve done this myself so I accepted the request but the person that requested the share was surprising.

    This DNA relative was predicted to be a 5th cousin at 10cM but that wasn’t the surprising aspect, what intrigued me was the fact that they were 100% African.

    I know I shouldn’t be so surprised about this since my grandmother was Afro-Caribbean. This is a highly interesting match simply because I had hopes of finding a Ghanaian relative being that my father’s highest African percentage is Ghananian but this person was not Ghananian, they are Angolan.

    My Fathers results vs his DNA relative
    23andme DNA results of an Angolan

    Being that it is such a small match there’s probably no way I’ll ever be able to discover which ancestor was fully Angolan. I assumed that this match would be from my Grandmother’s side since she was the Afro-Caribbean but the shared matches point to my French Grandfather’s side. There are seven matches between my father and his Angolan relative. Of the seven only one is not open to sharing their ancestry composition.

    Of the six relatives open to sharing I was able to view the DNA segments my father shared with these relatives. That particular segment in my father’s chromosome painting is identified as “African Hunter-Gatherer”. Our Angolan relative only has 0.2% African Hunter-Gatherer but people from the Congo Basin are Hunter-Gatherers of South Central Africa. There’s a very good reason why Angolan and Congolese are part of the same category on 23andme, I’ll explain that below.

    Angolan relative is purple
    Photo by Thijs Boom on Unsplash

    Now for a little history on Angola, before the Portuguese colonized Angola, there was a pretty sizeable Kingdom located in central Africa. This Kingdom called Kingdon of Kongo comprised of northern Angola, the western portion of the Democratic Republic of the Congo, the entirety of the Republic of the Congo, and the southernmost portion of Gabon.

    This Kingdom was a highly developed state and had an extensive trading center, frequently traded with neighboring kingdoms were natural resources, ivory, copperware, metal goods, raffia cloth, and pottery.

    In 1483, the Portuguese explorer Diogo Cão landed in the Kingdom of Kongo when he sailed up the uncharted Congo River. Cão left the Kingdom with some Kongo nobles and brought them to Portugal. The Kongo nobles and Cão returned to the Kingdom in 1485. The ruling king, Nzinga a Nkuwu, converted to Christianity. In 1491, Nzinga a Knuwu was baptized and changed his name to João I. Christianity quickly became the religion of the Kongo nobles.

    In the decades that followed, the former traded goods were quickly replaced by human trafficking also known as slavery. The Kingdom has a long history of slavery, one that predates the arrival of Europeans. It’s my belief that this fact is what made it a favorite source for Portuguese traders and other European powers.

    With this little bit of history, we know why on my father’s DNA painting his DNA segment shows up as African Hunter-Gatherer and our Angolan relatives show simply as Angolan & Congolese.

    One of the DNA cousins my father shares with our Angolan relative has two grandparents from St. Vincent and it might mean nothing but in the mid-1700s we had French relatives living in St. Vincent and this is probably where our Angolan ancestor ended up in slavery. It’s just a theory but I know which lines were living there and I’m conducting a little experiment to see if everyone from that line carries a little bit of Angolan & Congolese in their Ancestry composition on 23andme.
