      "renowned warrior"

      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.

Long form Louis is getting cool again and, with the Lewis spelling, is the Number 2 name in Scotland.

The name of Jacob's twin brother, son of Isaac and Rebecca, Esau could make an ideal twin choice, if you don't mind its meaning and the difficult story in the Bible behind the name, as convoluted and full of drama, tragedy, and reconciliation as any soap opera
