DNA results R1b-M269

Previous Y-DNA testing

The Seabury DNA Project currently only lists two 12 Y-STR kits, and they are a GD of 6 at 12 markers. Unknown if either of them are a patrilineal (all male line) descendant of Samuel Seabury. Both of these testers fell under R1b-M269, but with only 12 Y-STR markers tested, it is impossible to refine further.
