Ó Cuindlis
Ó CUINDLIS—I—Cundlish, Cunlish, Quinlish; 'descendant of Cuindleas' (an ancient Irish personal name); the name of a literary family in Connacht, who had a share in compiling the Book of Lecan. It would seem that this name was changed into Ó Coinleisc, which see. The same person is called Ó Cuindlis by Annalists of Loch Cé and Ó Coinleisc by the Four Masters. (See Annals, A.D. 1342.) The latter is the form now in use in Mayo.
