I've enjoyed reading the info you've shared on the various Edney lines and believe I've seen you refer to the Jonathan Edney line as well.
My Edney forebear was Love Edney (b. ca 1782 Eng -d. before 1820 NC), sister of Jonathan Edney (b. 1780 Eng-d. 1834 IN). Both were children of a Sir Jonathan Edney and an unnamed wife who never left England.
Recently I saw reference to the dad's name as "Jonathan Morrow Edney" and the son's as "Jonathan Robert Edney".That's the first time we've seen middle names for either. "Morrow" sounds like a surname -- have you come across any Morrow-Edney marriages in England in your research?
