The only Catholic parish I am aware of in the city of peoria was St. Mary's. I believe the "Old" St. Mary's came into being about 1846 or 1847. I think it was consecrated or somehow solemnized by the bishop of St. Louis. It was in existence until the new St. Mary's was built (this was about 1899, I think) (present-day St. Mary's prish AND Cathedral). The "old" church was then vacated and later torn down. I don't know if there was another church in existence at the time or not. Bill in Denver PS: If you are thinking about records, it's nearly hopeless!!!! I''ve been waiting nearly 8 months for a very simple request. Some of their old records were transcribed and printed in PCGS publications. Certainly not all. And they are scattered, hard to find.
