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.
A good first place to start is to search the database for your ancestor. Only persons belonging to a family are in the database. You can find website in the Resources page to help search for more persons.
You can visit the Facebook group for Kastlers, Kastelers, and Kastners. It has much of the same content as the website, but less organized. You can ask questions in the group to get full visibility.
