Surnames in Gruningen, Zurich, Switzerland - Wiederkehr
I am searching for my Wiederker ancestors in Catholic and Reformed Church Records 1418-1996 and find similar spellings to Wiederker. In the WIKI in FamilySearch Wiederker is the only listed surname for citzenship in Grunningen prior to 1875.
Other names listed are: Wiedekehr, Wiedersehr, Wildekehr, Widerfehr, Widerhehr
Are these different surnames than Wiederkehr or merely miss spelled form of Wiederkehr?
