I just discovered that today, through an obituary, that my ancestor was married by a Reverend CARR in 1839 in Allegheny County, PA (perhaps Pittsburgh). My ancestors were Mary McClelland and John Wilson. Both Mary and John were from Ireland and Mary was from County Tyrone. Does anyone know how to determine who Rev. Carr was? If marriage records are available from that time period, where is the best place to search? Thanks in advance, Rick Wilson New York, NY
