I am descended from Anna (Jenkins) Williams, who was the daughter of Ziba.What kind of info are you looking for?
I have Ziba as the son of Byron and Lucinda Jenkins, and maybe Byron descending from David and Elisabeth Jenkins.I say maybe because although I have this in my notes, I have not listed a source, so who knows how I made that connection.
Ziba and his wife lived with Leonore and Ellsworth Beck in Franklin County in their later years.I'm assuming that Leonore was their daughter, although I never proved that either.
I'm interested how you know Gustina's maiden name was Lightner and if it's possible the spelling varied as I'm unable to find any Lightners in that time and place.I have a special interest in Gustina's family for reasons I'll only share off-line.
That's about all I know right now, but I am working on this, and I am willing to share info as I find it.
