Levy

Jewish (Ashkenazic and Sephardic): from the Biblical personal name Levi, from a Hebrew word meaning ‘joining’. This was borne by a son of Jacob and Leah (Genesis 29: 34). Bearers of this name are Levites, members of the tribe of Levi, who form a hereditary caste who assist the kohanim (see Cohen) in their priestly duties.
