About us

The Project has identified and united current families in the Czech Republic with families living in the US.

There is a very interesting Y-DNA comparison study of the Moravian Valachs with samples from the Czech Republic and Central and South-Eastern Europe.  The study, published in June 2012, can be viewed at:

 The following data begins to provide some insight into the genetic substratum of the Czech Republic. One can see the genetic signatures of Slavs, Celts, and others

Note: The term haplogroup is a large cluster of people who share a founding father or mother.  Although both mtDNA and Y chromosome DNA both begin with letters, there is no relationship between their designations.  

Eupedia,com contains some great background information on the origins and phylogenetic trees of both mtDNA and Y chromosome DNA haplogroups.
