I've finally found the marriage record for Louise Kleinknecht and Joseph Wager (it was just recently digitzed) and their reverend was Paulus Heid. He was reverend of the Peoria German Evangelical Lutheran Trinity Church at that time. The church doesn't seem to exist anymore and I haven't so far been able to find much about it. I know its origin and who the reverends were, but no records. If the records still exist I don't think they're digitized. Does anyone have thoughts or know anything about the church? Thanks.
