Have you come across a James Allen in your dealings in Orange County, NC? My own Allens were located here in Washington County and Smyth counties in Virginia. I don't know my Thomas' father's name (Thomas died in 1843 at about age 40), but there was a James Allen who died in Washington Co VA in 1855. His place of birth was listed as Orange County, NC and his parents were Daugherty and Rebecca Allen. There was also a William Allen who married in Washington County in 1794, and a Samuel who married here in the same year. One of them may have had a son named Jacob, because a Jacob Allen married in Washington County in 1822. Any possible connection?
