Re: Y-DNA Big Y test #dna

I will give you a non-scientific example as to why you should NOT do
further Y-DNA testing for your stated purpose of finding matches.

My husband knew his ancestral location, and through the records of
LitvakSig, we were able to create a tree containing most of the
inter-related Jaffe families. His line goes back to Shakhna b. Borukh
born in 1782. Through Family Finder on JewishGen, we met a man who
should be related. In 2012, the two of them took a 67 marker test and
the results showed a genetic distance of 0. Our paper-trail indicates
that the man born in 1782 is the common ancestor.

Since then, the closest 67 or 111 marker matches have been three men
with different surnames at a distance of 1. These men could have
originally had the Jaffe surname which for some reason was changed, or
they could be related >from an earlier time before surnames. Since we
have a paper trail, this match gives those three men some clue about
their roots, but nothing more. They need to do more records research.

This month, after five years, my husband finally had a 37 marker 0
distance match to a man with the surname Jaffe. Initial inquiries show
his ancestors came >from the same town. We have not yet exchanged
detailed information.

Testing at 111 markers could only eliminate men who matched at a lower
level, not find more men. However, you might want to upload his
information to which is free. Big-Y will tell you
genetic make-up before the time of records. You may find matches to
men who only did a Big-Y test, but I think that fewer men have taken
that test because of expense. Thus, you could play the lottery or
invest the cash and wait for more men to test. If money is burning a
hole in your pocket, do an autosomal test for him. FTDNA can run their
Family Finder test with the sample your husband already submitted.
