Well, the name “Devlin” in Gaelic is a boy’s name meaning, “fierce courage.” I can think of no better surname for DS’ own alpha-male, Mr. Burke Devlin.
Of course, Irish activist/politician Bernadette Devlin McAliskey is very feisty herself, and has displayed “fierce courage” over the past fifty years or so.
Maybe Burke and Bernadette are/were cousins with roots in Belfast or Londonderry, Northern Ireland?
Erin go bragh!
