DNA 12% match
« on: Sunday 26 March 23 08:09 BST (UK) »
I did a DNA test hoping to find contacts for my birth father’s family.   I now have a 12% match with a young man.     Does this make him my half-nephew, i.e. that his mother and I are half-sisters?      My half-sister on my mother’s side gave a 25% match.   Any help would be appreciated.
