Re: general DNA question
It can only check the mitrochondrial dna line which is the all female line and yes it can provide matches to females, which can acutally be helpful For example Alley is my 6th grandmother, in all female line, I think, I am not sure if Wife #1 is my grandmother or Alley,
If I have an all female line to Alley or wife #1 and I take my mitrochondiral DNA and put it up agains female descendents known to be of Wife #1. Then I can prove Alley was the mother of my gggggrandmother.
you can also use this to prove fathers,.. sort of,
If Alley only had one husband.. chances are if you connect to her, he is going to be your gggggrandfather. Assuming she didn't step out on him and all.
