Status summary

Completed as of October 6, 2020:

  • Recruiting additional descendants of James Brown for further SNP testing - anyone interested in submitting their DNA for testing should contact Raymond T. Wing (email: wing.genealogist AT gmail DOT com)
  • Predicted to fall under R-L2 based on 111 STR marker test of a descendant.

Still to do as of October 6, 2020

  • NGS/WGS test for subclade under R-L2.


Biography

Parentage of James Brown

John Brown(e)[1] was born about 1591[2] and died at Rehoboth 10 Apr 1662.[3] He married by about 1616[4] to Dorothy _____ who died at Swansea 27 Jan 1673/4 "being the ninety and eighth year of her age or thereabouts"[5]. They had three children (daughter Mary and sons James & John).

First Generation

James Brown was born before 1627[6] and died at Swansea 29 Aug 1710. He married about 1655 to Lydia Howland. They had seven children; two daughters and five sons (James (II), Nathaniel, Jabez, Joseph and Hezekiah.

Second Generation

Josiah Brown, apparently never married.

(poss.) John Brown

  6. He appeared on the Able to Bear arms list of 1643, so was at least age 16 at that date.

Previous Y-DNA testing

The Brown-Browne-Braun DNA Study Project (Group No. 048) had one individual who claims his Most Distant Known Paternal Ancestor (MDKPA) was John Brown 1579-1662.[1] None of the individuals have done any Y-SNP testing and FTDNA simply predicts they fall under R1b-M269. One individual has done 111 Y-STR testing and plugging in his values in the Nevgen Haplogroup Predictor tool comes up with a possibility of the family falling somewhere under R-P312>>U152>L2, but with a low probability score (between 45.85% for the most likely to much less than 1% for others). In addition, the tool stated there is a 43.6% the family falls under an "unsupported clade".

  1. this group has other close STR matches who list various MDKPAs, but all are somehow closely related to each other.


NGS/WGS testing

NGS testing of Y-DNA descendants of John Brown (and ideally descendants of his son, James) would refine the placement of this family.
