Oliver was the son of Benjamin Kilgore's brother. William and Benjamin Born in PA to James and Elizabeth Jack Kilgore who had sixteen children. Have verified most of them at least through one or two generations from parents, however, am still learning and I appreciate much of what I am seeing on this post for later generations.
You may have already discovered this. I began working on the Kilgores many years ago as well - descendant of Benjamin through Isabella Kilgore Greer & her husband Robert Greer from SC.
Also managed to solicit many Kilgores to the FTDNA Kilgore project. Followed Benjamin, his family and many Greers to KY while tracing their kin back to Laurens .SC. Am always willing to share and compare.
