In my Allen ancestry, there was a John Allen Sr. b. 1726-1729 in Belfast, Northern Ireland who came to Savannah GA with wife Jane Beatty (and their children) around 1769 on a ship called Hopewell.Jane's father Joseph Beatty, was also on the ship. John Allen and Jane Beatty Allen settled in Burke Co GA or that area.However, your Allen and Beatty ancestors might be from the same lines, even though they are in NC.There may have been other family members on the ship who moved that direction.
John Allen and Jane Beatty Allen's children included (based on information from other Allen descendants):
James Patrick Allen b. 1750 Belfast married Francis Simmons Jane Allen married James McConkey then Louis Dunn Unknown Allen female married Robert Fleming John Allen, Jr. married Unknown William Allen migrated to LA Elizabeth Allen married John Martin Nancy Allen Isabell Allen Mary Allen
