This topic is the result of two recent Pomeroy FTDNA YDNA results. Research shows that they are descendants of Col. John Pomeroy (Pomeroy-127) , by two different sons; Francis, (Pomeroy-1698) and Thomas (Pomeroy-1878).
The Wikitree paternal ancestor of Col. John Pomeroy is given as William Holmes (Holmes-60) , husband of Martha Pomeroy. (Pomeroy-145). If the genealogy is correct, the YDNA would have come from William Holmes.
The results of both men were entered into Family Tree DNA Surname Projects: Holmes and Pomeroy.
The Holmes Project shows that while both men match each other, they do not match anyone else in the Holmes project. The Pomeroy Project shows they match each other and 27 other Pomeroys, all with early UK origins.
Sue, you raised an interesting point, which I did follow up on: That William Holmes and Martha Pomeroy Holmes may have adopted Pomeroy children. Assuming the genealogy is correct, and Lt Samuel Pomeroy was son of Edward Pomeroy (Pomeroy-322), it would be logical to look to Brixham for any Pomeroy children available for adoption, and who would most likely have been nephews of Lt. Samuel Pomeroy.
Not all of the children of Edward Pomeroy and his wife Wilmot have WikiTree Profiles, but the Brixham, Devon birth records record just four sons of Edward: (1608-1612) Thomas (1605-unknown1609), William (1606-1683) and Arthur, b. 1614, whose death is recorded in Brixham 1663). William’s descendants are well documented in Brixham.
While examining the Brixham and Devon birth records, we note that there is no birth record for “Samuel” in Brixham. No Samuel as son of Edward.
Adoption doesn’t seem likely. The History and Genealogy of the George Holmes Pomeroy family has many detailed pages covering the descendants of LT Samuel Pomeroy, their marriages, wills and legacies.
It is specific as to the chronology of events of the Thomas Holmes Pomeroy, and the compiler gives many suggestions as to how the Pennsylvania family tradition MAY fit into the “proven” chronology. Note he doesn’t claim the family tradition fits with the proven facts. At this point we cannot know what the facts are.
