SCOTO-IRISH, in History, an epithet applied, by some writers on Scottish antiquities, to the colony of Irish, commonly called Dalriads or Dalriadinians, who, in the beginning of the sixth century, established themselves in the district of Galloway; and formed a distinct tribe, till, under the reign of their king Kenneth II. they united with the Picts, whom they had nearly subdued.
