My mother's paternal side were/are Gill's.
My great grandfather was Lewis Gill. They lived in Chillicothe, Ohio. We know nothing of his parents.
From what we know, he was born May 1, 1843 in Zanesville, Ohio and died October 31, 1925 in Yukon, Oklahoma.
We know nothing about his siblings either.
Hope to hear back from you either way.
