Bishop and patron of Cork, born near Bandon, about 550, died at Cloyne, 25 September, 623, was son of Amergin. He evangelized Gowran, Coolcashin, and Aghaboe, and founded a school at Eirce. For some years he dwelt in a hermitage at Gougane Barra, where a beautiful replica of Cormac's chapel has recently been erected in his honour. Finbarr was buried in the cathedral he built where Cork city now stands. He was specially honoured also at Dornoch and Barra, in Scotland. There are five Irish saints of this name.
