Your data and mine seem to fit together.I am descended from John Johnson Hammonds (my gg grandfather), son of John Hammonds and Rachel. While her maiden name was believed to be Johnson, we had no middle name. I know of only two of John Johnson Hammonds' siblings, Charles and Thomas, about whom I know very little -- supposedly one moved to New Mexico and the other to California. After John Hammonds died (before 1812), Rachel remarried. She and her new husband, Joseph Hodges, as well as her son John J. and his family, moved to Texas, where they were recorded in a Mexican census about 1835. John J. and family were also in Crawford Co., Arkansas for a time before landing in Texas. Where did Abraham live?
Please let me know more about your data and your sources. I will be glad to send you what I have, although it is clear you have more on John Hammonds and family than I do. I have a lot on John Johnson Hammonds and descendants, but not much on his forebears. It is interesting to find an Ambrose among them -- that name occurs a couple of times in my line a couple of generations after John Johnson Hammonds.
