These immigrants are commonly referred to as the Pennsylvania Germans or the Pennsylvania Dutch.[6] The Pennsylvania Dutch are made up of Amish, Mennonite, Lutheran, German Reformed, Moravian, and other groups. Today, most Pennsylvania Dutch speak a variation of their original German language, as well as English.[7]
