If you are working with the church records for a particular town, you need to know the names of the nearby towns and villages. The trick is to find a contemporary map or gazetteer, since the town might not still exist.

Here is my (current) list of towns near Züttlingen, sorted alphetically:

Assumstadt
Billigheim
Bittelbronn
Domeneck
Ernstein
Hagenbach
