Status summary

Completed as of April 15, 2021:

  • Recruiting direct male-line descendants of James Barnaby for SNP testing - anyone interested in submitting their DNA for testing should contact

Still to do as of April 15, 2021

  • NGS/WGS test multiple descendants of James Barnaby to place the family clade as well as test descendants to discover any subclades unique to descendants lines

  1. While this child is known to be living in 1693, it is currently unknown if it was a son or a daughter.

DNA results R1b-Z36

Previous Y-DNA testing

The Barnaby DNA Project lists one individual claiming Y-DNA descent from James Barnaby[1]. This individual has not SNP tested and FTDNA predicted they fall under the R1b-M269 Haplogroup. They have tested 111 Y-STRs and plugging their STR values into the NevGen Haplogroup Predictor gives a prediction of falling under R1b U152>Z36 with a probability of 70.02% with subclades of R1b U152>L2 comprising several of the very low probability results also listed.

Further needed testing

We need additional direct male-line descendants of Samuel Rider (and preferably of his son Samuel [II]) to WGS/NGS test to confirm/refute this prediction and further refine the haplogroup/clade for the family.

  1. The project also lists a second individual who is a very close Y67 match who does not list a MDKPA (Most Distat Known Patrilineal Ancestor)
