12, 37 & 67 Marker test performed by Family Tree DNA

y-DNA 3/6/2019 

DNA that is carried on the Y chromosome can only be passed from father to son.  The Y-DNA for all of the above tested males descended from Heinrich Frey who was born in Germany in 1673.  In the 380 tests that are reported above, there are 373 exact matches.  Of notable interest is the fact that the mutation on marker 464a occurred from Heinrich to either his John or Benjamin.  If testing from additional descendants from son Benjamin all have marker 14, then it appears that the mutation probably occurred at this level.  The question is whether the mutation was to son John or to son Benjamin.  This question can be resolved if additional descendants of other sons of Heinrich show marker 15 then the most likely mutation occurred to son Benjamin.  If these tests show marker 14, then the mutation occurred to son John. 

Mutations randomly occur in nature and are shown in red, above, as a mismatch.  At this time, it is impossible to tell at which generation level, or with whom, these mutations occurred without testing all of the living Frey, Fry, Frye males that descended from Heinrich Frey.

If you are a male with the surname of Frey, Fry, or Frye and want to know if you are descended from Heinrich Frey, y-DNA testing should be able to tell you definitively.  CAUTION  There are several companies performing y-DNA testing for genealogical purposes and each one of these companies will use a slightly different set of allele markers to test and their reports will be in a different format.  Therefore, we advise you to use the same company that we have used, Family Tree DNA.  www.familytreedna.com
