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.


Parentage of James Browne

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

(to be added later)

  1. Anderson, The Great Migration I:420-429
  2. based on estimated date of marriage.
  3. Published Rehoboth VRs p. 804
  4. The Great Migration I:426
  5. Published Swansea VRs, p. 26
  6. He appeared on the Able to Bear arms list of 1643, so was at least age 16 at that date.

DNA Results R-L2

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.
