OK
So like the YDNA follows direct line father, son, grandson etc so the mtDNA
follows the line mother, daughter, granddaughter etc and the only time the
male mtDNA can be used to confirm a female relative is his mother or
sisters.

Hi, Bob-

You are correct about the use of the Y DNA testing--you could compare
Jeffery's male descendants with John's to determine whether Jeffery is
John's
father or not. If he isn't, you would have to compare other male descendants
you
know were fathered by Paul (if any) to determine whether he is the father or

not.

There is no way to determine for sure if Grace was John's mother or not
through mtDNA testing unless John is still living and can have an mtDNA test
and
the results compared to a direct FEMALE descendant of Grace's (daughter to
her
daughter on down the line). John WILL have inherited mtDNA from his mother
but he won't pass it down to HIS children.

Now with the mt DNA am a little confused of the line link that needs to be
taken to prove or disprove who his mother is. Assuming that it is Grace it
would have to be mt DNA from the sisters and half sisters of John, or
direct
female link to younger generation wouldn't it? But what mt DNA would it
have
to be from what male line to prove this also?

Nelda thanks for the link. I will see if I can make sense of it.
