Halberstam
Halberstam (Yiddish:האלבערשטאם, Hebrew:הלברשטם) is a Jewish surname, used by several branches of the Halberstadt family.
Halberstam, meaningless in its current form, is altered from an older name, Halberstadt, used by many descendants of Rabbi Tzvi Hirsh (died 1748), the rabbi of Halberstadt.
