I am new to DNA anlysis and am hoping someone can solve a puzzle in
my husband's FTDNA results. My husband's last name is GREENGARD.
Over the years we have collected numerous Greengard trees (that all
point to an origin of Virbalis, Lithuania and also point to them
being one family) but have had a hard time connecting the trees.
Several of the Greengard descendants can go back to their 3rd
gr-grandfather , but with my husband Tom we can only go back to his
gr-grandfather. We've made some progress, but decided to have two
male Greengard surname descendants test their Y-DNA-37 markers at
FTDNA. One is my husband Tom and the other is another Greengard.
The results are as follows:
The other Greengard descendant shows up as a potential 2nd to 4th
cousin of Tom in Family Finder. In the actual 37 marker charts, Tom
and this other Greengard differ on DYS464c, DYS464d and DYS CDYb.
This makes sense to me.
However, another individual with a completely different surname
shows up as an exact Y-DNA37 marker match. But he and Tom do not
show up as related in Family Finder. This individual can trace his
lineage via his different surname back to the 1750's. Interestingly,
this individual traces his lineage also back to Virbalis, and his
ancestors stayed with Greengards in NY when they first come to the
Can anyone explain why someone with a different surname, has an exact
Y-DNA 37 marker match with my husband, can trace his lineage via that
other surname back to the 1750's, yet doesn't show up in Family
Finder? Clearly there is some tie to the Greengards since his
ancestors stayed with Greengards in NY upon emigrating.
