This project seeks to trace and connect descendants of Wolf of Küps (ca. 1696- ca.1770). The two main ancestors are Wolf’s sons, Moses and Jakob (known by the Yiddish diminutive, Koppel). When required by the German government in 1813 to adopt a family name, Moses evidently chose the acronym Moses aus Küps, which became MACK (the “C” was added later). Jakob/Koppel (also known as Robert) reportedly chose the acronym Robert Aus Ulm (where he may have lived), with the “H” added later, to become RAUH. Other stories derive the name from the Hebrew word for "rabbi"; a third possibility is that it derived from the German word for "rough." Mack and Rauh descendants are encouraged to contribute to this project by adding profiles and by correcting and adding information. Thanks go out to Jonathan Mack, Walter Mack Goldsmith, and especially to Michael Wallace Rich for the hours of work on the family tree.
