DNA Update

Have I found any common ancestors through my DNA matches at 23andme?  No.  But I am still hopeful.  I have more  people to contact- matches for both parents and me.  When a genetic match shares genomes, I can see where the common segment or segments lie and who else overlaps.  I have over twenty people matching me at the beginning of chromosome 7, but only one person matches on chromosome 5.  In theory, all 20+ of us are related from the same ancestor- if only we could discover this ancestor.

As the database grows, so does my chances of finding more matches and discovering the connections.  In the meantime, I am more motivated to uncover older generations on each line.


As of today, I have 1006 genetic matches in the database.  I can contact five people per day to ask them to correspond and share genomes.  About 50 of the 350 that I asked to share have accepted.  I am working with a very small sample size of genetic matches, so I am not too surprised that I have not figured out any connections yet.  I also have not figured out a way to inspire people to respond to my inquiry.
