German-Jewish Naming Practices:

Others used names for which they thought they had an historic connection. Cohen and Katz for priestly descent, Levi, Levy and its derivatives for tribal descent. 

Then, slightly further removed from the tribal names, are names that come from the German word that translates the Hebrew word for the animal that symbolized the biblical tribe or person. 

For instance, the lion is the symbol for Judah. Loewe (actually Lowe with an umlaut over the o) is the German word for lion. Loev, Loew and Loeb are archaic German forms of Loewe. So, all the Loebs, Loewes, Leons, Leupolds, Leopolds and so on are germanifications of Judah. 

Likewise, Benjamin’s symbol is the wolf which explains all the Jewish Wolfs, Woolfes, Wolfsons and suchlike. Hirsch is German for deer which is Naftali’s symbol
