My gg grandfather was John W. Whitehill. He was born about 1860. He married Martha Freeland of Greene County, PA. They had many children, one of which was my g grandfather, David Cyrus Whitehill, who married Hazel Emma Dunn. Both the Freeland and the Dunn line go far back, but I am at a standstill with John Whitehill. I don't believe he was born in Greene, PA. If any of this sounds familiar, I'd appreciate any help.
