Y-37 match genetic distance 4
Hello
I have Y-DNA march on Y-37 level with 4 genetic distance.
When could we have the common male ancestor?
The match got NPE in late XIX century so surname is after mother of his x-greatgrandfather.
What is important the mother of his x-greatgrandfather few years later had married some man and got few children with him. So I think it could be a father of illegitimate match's x-greatgrandfather.
