Where to Look for Genealogical Records in Alsace by: Suzele
I'm no expert on the subject...here is what I do know about researching your family tree in Alsace...
After 1792 you can find records usually at the Mairie (city hall) of the village or town where the person was born, got married, or died.
After 100 years you can find these records at the "Archives Departementales".
In Alsace there are two departements:
1) Haut-Rhin or southern Alsace 100 Avenue d'Alsace 68000 Colmar, France
2) Bas-Rhin or northern Alsace 5 rue Fischart, 67000 Strasbourg
Before 1792 you'll have to check the Parish Church records which you will find at the "Archives Departementales" most of the time, possibly the library, the parish church itself, or the Mairie (city hall).
Another source of information for French genealogical records to check out is Geneactes.
Some of the French records (over 100 years old) have been scanned and put online.
