Joe, I am also looking for Gillespie's in Pa. My g.grandfather is Henry. I found him listed on the 1870 (age 45) and 1880 (age 48) Cambria Co. census only. Both list that he was b. in Ireland. His children were baptised at St. John Gualbert's catholic church. There is also a Mary Gillespie that married James Connor (O'Connor) that I believe may be Henry's sister as they are godparents to each others children. Tom Kinney
