Your listing for Isaac Allen (1765-1820) in Allen, Weathrford And Others is the first family history information that shows him as having been born 15 Aug 1765, Orange County, North Carolina, died: 1820, Allen County, Kentucky. Previously, he had been listed as born 1779, Virginia, death date and place unknown. This seems to be the same Isaac Allen who married Nancy Graham, by whom he had eight children, including Millington Allen (1802-1884), with whom she is living near and is widowed with six children in the 1820 Census of Allen County, Kentucky. Isaac and his family were in Chester County, South Carolina, and Millington was born in South Carolina in 1802. Information concerning Isaac's children is a bit shaky, but the census information does seem to confirm Millington was theirs. I would be very interested in what you know about Isaac.
