From the experts:
This is an Anglicized form of various names; the Irish Gaelic O Bruic; German, Bruck or Breck, meaning "swamp" or "wood"; Yiddish, Brik, "bridge"; and Slovenian, Bric, "dweller from a hilly place." Gosh, and we thought it was just a macho word name invented by Tennessee Williams for the hero of Cat on a Hot Tin Roof.
