Shannon.—This name in Kintyre and the adjoining districts, and in North-East Ulster is the anglicised form of a sept of the McDonalds in Kintyre. It was earlier written O'Shanney. A Rev. Malcolm Mac-O'Shannon was minister of Kilcolmkill and Kilblaan, Kintyre, in 1630, correctly written O'Seanáinn. We find it anglicised M'Shannon in Co. Antrim.
