LOEWENHEIM and related surnames e.g. LOVENHEIM, LÖWENHEIM, including WANGENHEIM & DEWITZ, as well as close Y-DNA matches (Haplogroup E-L117, E-M123 & E-M35) that might share a common male ancestor at a time before surnames were adopted. Predominantly looking at families of Jewish Ancestry, but all are welcome to join. As inherited Jewish surnames were not generally adopted in Europe before around 1800, living male-line relatives can have completely different surnames. As an example of brothers with different surnames, three brothers adopted the surnames LOEWENHEIM, WANGENHEIM & DEWITZ in 1812 in West Prussia. LOEWENHEIM families can be traced back to various parts of Germany, parts of which are now in Poland, and to Hungary. Y-DNA tests would reveal which share a common male-line ancestor. Any men with Y-DNA belonging to Haplogroup E, and subgroups such as L117, E-M123 & E-M35 are welcome to join the group.
