Thanks for responding. No, it's not St. Philip in East St. Louis. I have those church records from familysearchlabs online. I grew up one block from that church. This St. Philippe I was asking about was the mission church for Ft.De Chartres in Randolph County, I have since learned since by my original post. Their records are also on the same website with the Illinois Diocese of Belleville ones - but since it was an early mission, the extant records are mixed up with St. Joseph in Prairie du Rocher - I was trying to place it in a town. Thanks anyway.
