I'm looking for the marriage date for Elisabeth Voisin, who married Louis (Ludwig) Rauschkolb sometime before 1849, possibly in St. Clair County, IL. Elisabeth was born in Ruchheim, Germany, in 1822, and was confirmed there in 1836. Sometime after that, her family came to the US. Her parents were Jacob Voisin and Elisabetha Hausam.

The first record I have of Elisabeth and Ludwig is the birth of their son Louis in Belleville in 1849, but I don't know if there were other children before that.
