Anonymous, not sure you're still around, but how is Esther a cousin to Mary Ball? I know I've seen the Glasscock name associated with the Ball family, but I can't now find a cousin for Mary by the name Esther.
She had a half sister Esther, but that Esther married Rawley Chinn.
Elsewhere (a Glasscock listserv), I find:
Esther Ball was the daughter of Captain Richard and Sarah (Young) Ball. Hayden, p. 62-63
I've checked Hayden, and that's what he says. Captain Richard Ball was son of William2, and grandson of William1 Ball-189.
I will attach Esther to that profile.
