mt DNA results

[gilmore]

So from what I understand, if I want to check up on my mother's father's line, I would actually need to get my uncle (mum's bro) to donate a DNA sample and send it off for yDNA testing?

Of course, I really should do my own yDNA, too... my dad was adopted. His biodad was a Laing, which I think is a Scottish name, too. But who knows?

That's right. To get matches on your mother's patrilineal ancestry, you would need to test your maternal uncle's Y DNA.

If I were you I would indeed be interested in discovering my biological patrilineal ancestry. But that's just me. I can't leave well enough alone.
