I don't have a difinitive answer about the birthdates of Elijah and Micajah.But there is a clue the Edgecombe NC Court Minutes - (partial) 1757-1784
Mar 1762: Edmond Revel is a hand in the laying off of a road.
May 1771:Elijah and Micajah are listed as hands in laying out a road
August 1771:Elijah and Micajah are listed as hands in laying out a road.
How old would one have to be in 1771 to be assigned as a worker on the construction of a road?I would say at least 12.So that would put the birthdate for the younger of the two at least as early as 1759.
I would like to see a photo copy of the actual transfer deed recordings rather than the extracts in the books.
