About us

This project was set up to research the ancestry of a predominantly Jewish cluster of haplogroup J2a4b1 (J-L556, L560).  This cluster is currently comprised of over 200 families with different surnames and geographical roots. These families share matching or near matching 67 marker Y-DNA results as well as anomalies in their DNA signatures that make it a virtual certainty that they have a common paternal ancestor within the last 1,100 years.  New families exhibiting those DNA matches and anomalies are sought, to delve further into the likely origin and lifetime of that common ancestor, as well as into the migration paths of his descendants. The name of the group, WIRTH, is an acronym representing the first letters of the group's founding families.
