Need help finding information on this marriage. Both were married on 5/25/1875 in Linz, Austria. They also had three children born in Linz, Austria before coming to th USA in Oct of 1879. Supposedly they changed their last name to Tamm when they came to US. Trying to find information to locate the true last name. Francis was born in Wallau, Germany on 5/5/1848. Any information will help.

Thanks,
Scott Tamm
