I had initially believed that most American members of the Zumbrunnen and Zumbrun family descended from Heinrich Zumbrun, who immigrated to America in 1754.
I’ve since learned, however, that in fact at least 8 different groups of our extended family had arrived in the U.S. by the late 1800s. Here’s an overview of these different immigrations, when and where they initially settled, and the different permutations of how people spell the name. This page is a work in progress, so if you have any more information on any of these families, please don’t hesitate to get in touch.
