Brogan

Brogan or O'Brogan, is a surname originating in Ireland, anglicized from the original Ó Brógáin. The form McBrogan, is also present sharing the meaning of O'Brogan, essentially "son of Brogan."

The name is an anglicized form of Irish Ó Brógáin (“descendants of Brógán”), probably from a diminutive of bróg (“shoe”), which is ultimately from Old Norse brók (“breeches”).

The name has also been traced back to ancient King Breogán, and Saint Brogan (Broccán Clóen), Saint Patrick's nephew and scribe, and has many original meanings, including sorrowful, sharp-faced, sturdy and strong.

Traditionally, Brogan has also been used as a first name for boys, after the Saint. Provided by Wikipedia
