The Martyrology of Donegal records the name of an otherwise obscure Irish holy man, Colum, Son of Blann, at September 2. Canon O'Hanlon can offer only the briefest of notices:
St. Colum, Son of Blann.
St. Colum, Son of Blann.
The name of Colum, son of Blann, is inserted, and he was venerated, at the 2nd of September, as recorded in the Martyrology of Donegal.
