[Ger-Poland-Volhynia] DNA database

[Krampetz at aol.com]

Do any of the DNA database's allow anyone to see if specific surnames
had registered their DNA?
 
I've not been interested in this as I was looking for real  cousins.   But,
if I were to find a couple of surnames of my not-too-common surname  or
others in my tree,  I could much more easily be persuaded to take the 
test..
 
I looked at 23andme,  and they are certainly not thinking like I  am..
