Liev Schreiber's birth name is Isaac Liev, Liev after his mother's favorite Russia author, Leo Tolstoy. Though Liev is increasing in popularity in the secular world thanks to the actor, it originated as a Yiddish diminutive.

Lazer has some biblical cred as a form of Eliezer, Eleazar, or Lazarus, all relatives, and it's also a modern bad boy name a la Ranger and Breaker. Our recommendation would be to use one of the biblical forms as the proper name and Lazer as a nickname.

Appealing name because, in German and Yiddish, it also means "dear" or "heart".
