GIACR: German Immigrants in American Church Records
The retired BYU professor Dr. Roger Minert created a series of books called "German Immigrants in American Church Records". It contains names of German immigrants that have a town of origin (or last residence) in Germany listed next to their marriage or death entry. Copies of several volumes can still be purchased through the author's website. Surnames can be found on the publishers site of the available volumes.
