Here are some possibilities:
* German origin: Lemberg is a German surname, possibly derived from the place name "Lemberg," which translates to "lime mountain." There are several towns and villages in Germany named Lemberg, so it's possible that the surname originated as a toponym, meaning it indicated the person's place of origin.
* Yiddish origin: "Lemberg" was the German name for the city of Lviv (now in Ukraine), which was historically a major center of Jewish life. Thus, the surname may be a form of Jewish matronymic, meaning it was derived from the mother's name, potentially based on a woman named "Lemberg" or "from Lemberg."
* Polish origin: The surname could also have Polish origins, as "Lemberg" was a significant city in the Polish-Lithuanian Commonwealth. In this case, it may also be a toponym, indicating someone who came from Lemberg (Lviv).
