Brogan is a cheerful Irish surname that would fit right in with the Logans and Br-starting names now trendy for boys. It's been on the pop list for the past three years, though it's sliding again. Its history includes Saint Brogan (Broccan in Gaelic), who was Saint Patrick's nephew and scribe.
In "Shrek Forever After" Brogan was an ogre voiced by Jon Hamm. Supposedly, the character was almost called Gnimrahc--or Charming spelled backwards. Brogan is better.
