This website is dedicated to my great grandparents Charles Kastler and Juliette Kleitz, and great-great grandparents Jakob Kastler and Katharine Rathgeber. It was because of them that I started my journey into genealogy. I discovered not only my German heritage, but also my German family.
The map shows the larger family groups known at this time. The Kastler and related families on this website originated from the German-speaking countries of Germany, Austria, and Switzerland. Borders changed periodically, and prior to World War I, the Alsace region of France was part of Germany. Alsatian is an Alemannic dialect closely related to Swabian, although since World War II most Alsatians primarily speak French. Detailed information about the different families can be found in The Clans.
