Interestingly enough, Stratton as a a first name appears in my line a few generations after the Abney line.
Stratton Davis Foster, born in Rockbridge County, Virginia in 1891, son of Sidney W. Foster. Sidney = son of Thomas F. Foster and Malinda Garland. Malinda Garland = daughter of Fleming Garland and Elizabeth Wade. Elizabeth Wade = daughter of Daniel Wade and Melinda "Linny" Witt. Linny Witt = daughter of David Witt and Sally Abney. Sally Abney = daughter of Dannett Abney and Mary Meredith (?). Etc.
I do not know if Stratton was named for family but it appears to be a name that does not appear in any other related families at the time in terms of my line and is a unique name. Just a thought.
