The tribes of Galway were fourteen merchant families who settled in the town between the 1230s and the 1540s and who held power and prestige until the early decades of the twentieth century. They were not tribes in the usual sense. The term was apparently adopted by the townspeople themselves or used as a derisive term by Cromwellian soldiers.
Among the most ferocious of the tribes were the Blakes... famed as soldiers.
The Browns — no mean fighters, either — are sometimes known as Bruen.
One of the first casualties at Gettysburg was a D. Bruen. A Richard Bruen is reputed to have skinned his enemies. Richard respected and feared a local warlord and eventually killed him. Donning the skin, he tried to literally become the man he’d admired.
