I too, am a descendant of Elizabeth Jarman and Edward Morgan. I got the gedcom file from Ed in 2005. No sources sited.
GEDCOM FILE FROM:
Edward Boone Hudgens Jr. 1441 Wexford Downs Lane Nashville, TN 37211 615-333-9859 email@example.com
This was the address, phone and email listed on the gedcom file I got from Ed. Hope it is still current. Haven't corresponded with him in a long time. He sometimes posts on Boone and Hudgens genforum sites. You might be able to find his current postings there.
(Rumor has it that she was actually the daughter of a Pennsylvania farmer named John Jarman but no record of him exists anywhere in research or census records either.)
