DALRIADA  , the name of two

ancient Gaelic kingdoms, one in Ireland and the other in Scotland . The name means the home of the descendants of Riada . Irish Dalriada was the district which now forms the northern part of county Antrim, and from which about A.D . 500 some emigrants crossed over to Scotland, and founded in Argyllshire the Scottish kingdom of Dalriada . Fora time Scottish Dalriada appears to have been dependent upon Irish Dalriada, but about 575 King Aidan secured its independence . One of Aidan's successors, Kenneth, became king of the Picts about 843, and gradually the name Dalriada both in Ireland and Scotland fell into disuse, See W . F . Skene, Celtic Scotland (Edinburgh, 1876-188o) .
