I see that here on Geni the parentage of Elias Jernigan are uncertain, so I thought I'd share this info from Ancestry. I have many Jernigan and Coleman DNA matches on Ancestry, since I'm a direct descendant of both families. Anyway, some of them show this Elias' father as Frederick Jernigan:
Frederick JERNIGAN
BIRTH1749 Wayne Co, NC, USA

I don't know if the info is correct, but maybe has some clues. ?
