Nailed another DNA link. After pestering my cousin Neil for years to get his DNA done, I finally found a match with his son Dion on GEDmatch yesterday. That brings the confirms up to:
Both parents
All four grandparents
5/8 great-grandparents
4/16 great-great grandparents
Been a great week for genealogy!
Edit: Correction, there are FOUR great-great grandparents tagged, not two. I had missed tagging a couple and only just noticed.
