      "hairy"
    • Description:

      Esau is one of the neglected E-beginning boys' biblical choices--it's been off the popularity lists since 1902!

      Diminutive of Louis or Lewis, French and German
    • Meaning:

      "renowned warrior"
    • Description:

      Lou, all by itself, is become fashionable for girls, which usually makes a name LESS fashionable for boys. But Lou, like Bill or Jim, is rarely used on its own for boys anyway. (You wouldn't name a boy Frederick Lou the way that girls are named Mary Lou or, in the case of Keri Russell's new baby, Willa Lou.) Long form Louis is getting cool again and, with the Lewis spelling, is the Number 2 name in Scotland.

The name is extremely rare as a given name but has seen occasional use since the film's popularity beginning in 2010. Gru has a distinctive brevity that makes it memorable, with just one syllable and three letters. While some parents might choose it for its association with the reformed villain character known for his intelligence and eventual kindness, its rarity suggests most families still consider it too closely tied to the fictional character for mainstream use.

      Hebrew
    • Meaning:

      "Jehovah is God"
    • Description:

      Rarely used in the last two centuries, but might be worth dusting off and holding up to the light.
