Padraig Mac Giolla-Domhnaigh

Bradly—This name is the anglicised form of O'Brolchain in Derry and Donegal. This name is found in Lancashire from an early date and, I believe, is of Norse origin. Amongst the list of Rectors of Bury Parish Church we find "Roger Bradeley, Rector of Bury Parish Church, 1442."
