23andMe: Good News?

Image
From 23andMe email last week Recently in genealogy DNA circles there has been a lot of worry about the future of 23andMe , the second-largest DNA database. There is reason for worry , as Kitty Cooper said in a September  blog post : "23andme has been in the news this week because its entire board, except its founder, Anne Wojcicki, resigned over her plan to take it private again. It went public in 2021 but has yet to turn a profit and the WSJ reports that it will run out of cash next year."  Cooper asks, " Why is 23andme not profitable? ...Discovering what health issues you might be susceptible to because of your DNA is not a big motivator for getting tested. Many Americans want to know their ethnic roots, for example, do they really have a native American ancestor? Genealogists may be the largest group who are interested in these tests in order to better understand their family history and find new relatives. Therefore once Ancestry.com started selling DNA tests, withi

  This story revolves around the complex family ties and the mystery of Robert Keith Marvin's parentage. Born Charles Audrey Rice in 1922 to Harriet Rice, he was adopted by Ray and Jesse Marvin and renamed Robert Keith Marvin. The adoption was recorded in the Marvin Family Bible, indicating the family's awareness of it. In 1942, Robert accidentally discovered his adoption when he requested his birth certificate. The truth about his biological parents remained a mystery until DNA analysis in 2017 revealed a connection to the Bonebright family line, suggesting that Elmer Bonebright and Harriet Rice were his real parents. Robert passed away in 1970, never knowing his true origins, which were only uncovered nearly a century later through DNA science and his son's determination.   The story begins In the tapestry of family history, few threads are as entwined with mystery and discovery as the lineage of Robert Keith Marvin. Born amidst the snowy peaks of Helena, Montana, in the

What to Do When You Don't Know What to Do?

We've all been there. Lots of things to do, but ..... Stymied. This feeling signals to me that I need to clear the decks, clear up unresolved issues, and maybe chart the progress so far! I recently viewed a webinar by Blaine Bettinger on the genetic family tree compared to the ancestral tree. On a fan chart, the concept is quite clear, and you can see his images here: https://thegeneticgenealogist.com/2009/11/10/qa-everyone-has-two-family-trees-a-genealogical-tree-and-a-genetic-tree/ Pinterest.com Genetic Family Tree I'm listening to a lecture by Tim Jantzen about using autosomal testing for ancestors into the 1700s, and he says, At 10 generations back in time, perhaps only about 12% of one's ancestors are contributors of autosomal DNA to your genome; only about 12 of your 1024 ancestors are your genetic ancestors. [1] I think it is a worthy goal -- paint or otherwise triangulate DNA matches from as many ancestry lines as possible and denote them on a fan chart, and see w
