Question: is kerr an irish name?
Answer: The well known Kerr surname has long existed in Ireland, and originates from several distinct sources. In County Galway it was an Anglicization of O Carra, a patronymic name referring to a descendant of Carra; the word Carra in turn meant "spear." in County Donegal, Kerr was the Anglicized form of Mac Giolla Chathair.
