I've come across a number of surnames of the form Levi-[Something]:
- Tullio Levi-Civita was from an Italian Jewish family.
- Claude Lévi-Strauss was from an Alsatian Jewish family.
- Rita Levi-Montalcini was from an Italian Jewish family.
Does Levi- as the first half of a surname generally derive from (or is it) an indication of a Levite family? (I'm asking in general, not about those three families specifically.)
