Some things I know about the family name Lampert: 1. It means "Leopard" in Yiddish. 2. My relatives are Leviim. This status is passed down patrilinearly, with the family name. 3. My relatives came from a German-speaking area of the Carpathian mountains in what is now the Ukraine. 4. There are towns named Lampertheim in Germany and France, but I have no knowledge that the family name is related to either.
