Sarah you may know this by now. The Freiderich Klusmeyer & Caroline Beckmeir you are looking for was married in St. Louis, Mo. Feb. 4, 1855 at the Trinity Evangelical Lutheran Church. The pastors' name was Gottlieb Schaller. Sometimes the churches of that period kept records of their members. I hope this helps. As I look for my relatives this man keeps popping up. So he should not be too hard to track down. Good luck, Betty.
