Well, Rodham, Sr. was on the 1800 Johnston County, North Carolina census and wasn't found by me on any 1810 state census. It's logical to assume he moved to Tennessee with his daughter and sons, but nothing's been found to prove what happened to him. Rodham, Sr. was the son of John and Susannah Douglas of Northern Neck, Virginia. Records were found of the birth of some of John and Susannah's children, but Rodham is documented in John's will dated about 1772, if the date is remembered correctly. Susannah may have been Rodham's stepmother as well.
Genealogy is full of mystery.
There were so many John Douglases in those and nearby Virginia Counties back then, it may be impossible to ever pinpoint which one is ours. A search of those county records and ships' passenger lists just opens more possibilities for more Johns. Unfortunately, the names John, William and Edward were common names in our line back then. Rodham was such a unique and easy name to research. After years of research and not being able to document my speculations, I'll venture to say we may be descendants of the early Jamestown William Douglas or the Edward Douglas found in the Eastern Shores of Virginia.
