The old farm house at Fatland farm, Halsnøy Island, June 2015
This morning I woke up all excited because I realized that a large piece of my X chromosome comes from my Norwegian 4th grandmother Metta Olsdatter Ve (Fatland) born 1729 on farm Fatland, likely in the house pictured here. She died in 1805 on farm Ve (or Wee) so made it into the 1801 census.
So how did I figure this X inheritance out? My Dad and I share 33.5 cMs of the X chromosome with my fourth cousin once removed Maria and her mother (so it is phased). They descend from a different wife of our common ancestor Aamund Bjørnsen Tvetden. So these 3326 SNPs of X located from 68M to 113M must come from him and therefore from his mother Metta.
No I did not share this insight with my husband when he brought me my morning coffee. I know better than to make his eyes glaze over … only other genetic genealogy aficionados would appreciate this, so I am sharing it here instead.
It really makes sense for a DNA company or third party DNA tools site to let you link to your profile at a genealogy site rather than reinventing the wheel with their own tree software. So DNA.land now has a feature where you can link your GENI profile to your DNA results page. Then your matches can view your family tree at GENI to see where you might be related.
Last fall I blogged about DNA.land -a nice new web site created by Erlich Lab (a non profit associated with Columbia University). The idea is to have you upload your raw DNA test results in order to contribute to their research and then you get some DNA features in return. The privacy is good: only your matches and the relatives of matches can see your profile and where your DNA matches theirs. So perhaps get your ancestry matches to upload their data there if they are leery of the more open GEDmatch.
At Rootstech I attended a talk by Dina Zielinski from Erlich Lab about DNA.land and the power of big data. She played a wonderful video (above) showing human migration as seen from Erlich Labs analysis of the birth places of 43 million public profiles from Geni.com Continue reading →
Rootstech is over and I am exhausted. This year I was up early enough to go to the keynote sessions almost every morning. Wow! In a huge hall we saw great multimedia presentations over many screens while listening to a star speaker. I particularly loved Paula Madison and her Finding Samuel Lowe: China, Jamaica, Harlem; so of course I bought the kindle version of the book. [update: the pictures are better in the physical versions but it is still a great read]
Perhaps it is because of my work with adoptees and DNA that I so appreciated her story, but more likely it was just that she was terrific and the tale was so well told. I also got to see the short form of her documentary at the media dinner, definitely worth seeing.
My other favorite keynote speaker was David Isay and his StoryCorps. His concept is to get two people in a booth, facilitate their conversation, and record the result for posterity. I think the story I liked best was the one where the boy with Asperger’s interviews his mother – Sarah and Joshua. But every snippet he played for us brought tears to my eyes, the wild grandad, my son the veteran, and the boy who became close to the mother of the boy from the rival gang that he had killed.
Usually my favorite things at Rootstech are the exhibit hall, networking with fellow genetic genealogists, and learning a few new things. This year I have to add to that the sensational MyHeritage after party (click here for the slideshow over at Geneabloggers) and the Keynote sessions.
