John Fleming, b abt 1813, was residing in Westmoreland, Oneida, NY in the 1855 census. It also states that he had been here two years. It wouldn't surprise me to learn that he was at one time in Bennington, VT. His third wife was Jane Guiltinane. My ancestor was Margaret Fleming who married Patrick Guiltinane. They were also in Westmoreland. Could this be the John Fleming that you are looking for? Kathy Williams
