There are three primary genetic families that our Y-DNA evidence (i.e. paternal line) has revealed so far. Based on genealogical records, these three genetic families come mainly from three common ancestors (i.e. DNA alone cannot yet group our results by specific common ancestors). These common ancestors helped shape early America.
Genetic Family 01 has Scandinavian DNA and appears to have come from Sweden and settled in early Delaware (i.e. New Sweden colony).
Although many amateur genealogists confuse this family with the other two genetic families, data from this project definitively proves that this genetic family is unrelated (within a genealogical time frame).
1) Johann Gustafsson (c1618 Sweden – 1682 Philadelphia PA) is believed to be the patriarch of our Justice NC/GA/AL line. The circumstantial evidence suggests this is the case, but we are still waiting for Y-DNA confirmation from a known direct male descendant from Johann.
Genetic Family 03 came from England and settled in early Virginia.
2) William Justice (c1625 England – 1664 VA) m. Mary Frame c1656
Genetic Family 04 came from England and settled in early Halifax MA and Halifax County VA.
3) John Justice (c1696 England – 1766 Halifax Co VA) m. Mary Moore c1728
We also have many others that have tested and are from different genetic families. We are looking for more data to further understand the genealogy of these lines and better group them into genetic families.
