A large number of our Alsatian ancestors came from Soufflenheim, north of present day Strasbourg in Alsace, France. Soufflenheim is very close to the Rhine River and the former Duchy of Baden in Germany. Another large number of other early settlers came to Maryhill from villages just south of present day Baden-Baden in Germany. The early records of Maryhill cite these places of origin.
All these settlers spoke German but the area passed back and forth between French and German control over several centuries.
