I'm not sure if I'm part of this bunch of Brittons but I believe it's possible. I found the following, which I believe is your project:
FAMILY GROUP 5: Line of Richard Britton of Batcombe, Somerset, bc 1585. His sons Nathaniel and William settled on Staten Island New York and son Cananuel settled in Chester Co., PA.
Group 5 divides into two subgroups based on results for DYS 388. Several members of 5A trace descent from James Britton bc 1704, who moved from Chester CO, PA to Orange Co, VA in the 1730’s and from VA to Rowan Co, NC in 1754. All members of 5A have a value of 11 at DYS 388, whereas members of 5B have the modal value of 12. No one in 5B appears to descend from James Britton. Two members of 5B have traced their line back to Richard Briton bc 1585, B-22 who descends from Richard’s son William and B-33 who descends from William’s brother Nathaniel.
Subgroup 5B:
Lineage for A-17:
John Britton
William Britten, b. 1791 in Pa. Married in 1822, NY, to Margaret A. Dama; moved to Michigan in 1840. Died circa 1865 in Atlas twp, Gennesee Co. Mich.
John Britten, b.Dec.20, 1815 in NY m. Sophia Blocker in NY; died Dec 5, 1900 Orchard Lake, Mich
Azell B. Britten, b. Nov 19, 1872 in Ortonville, Groveland twp, Oakland co. Mich.; m Amy Ann Henderson Dec. 15, 1894 in Danville, IL.; died April 19, 1913 in Provo, Utah
I'm a direct descendent of John Britton noted at the head of the pedigree. Azell was my great-great uncle. I'm trying to find information on John's parentage. Though I suspect that he was a descendent of the Brittons who emigrated to Staten Island NY, I have no confirmed links. I don't know if you can help but I would appreciate any information you may have.
