Subject: Suggestions on Interpreting an Unusual DNA result?
Date: Thu, 7 Oct 2004 12:43:08 -0700 (PDT)
I just received a new DNA result on my Snyder DNA
Project and it is somewhat unusual. I could use some
help on interpreting this one.
One of our family's ancestors is John Snyder, born
abt. 1797 in Pennsylvania. We tested this line
against two other's we believed there was a possible
genetic connection to: Johann Dewalt Schneider, born
1755 in Germany, died 1828 in PA, and Adam Snyder (abt
There was an exact 25 marker match between the Dewalt
and Adam Snyder lines. However, Dewalt's results also
came back with an unusual mutation - a extra marker at
464 (464e = 16). Adam's results did not reflect this
I received John Snyder's results today - there is a 24
out of 25 marker match between these participants (and
they are all haplogroup I) - clearly, they are all
branches of the same Snyder lineage. However, John's
line also has the extra marker at 464e.
Genealogists previously believed that John and Adam
Snyder might have been brothers. Given the fact that
Adam's results don't have the extra marker, but
Dewalt's and John's lines do, does this preclude a
possible sibling relationship between John and Adam?
Thanks for any help or suggestions.
