re: Origin of Adair from Kildare name and possible connection to Sorley Boy. Refer "Topographical Dictionary of Ireland" page 30.ANTRIM. In ancient division of the Ireland the southern & S.W. parts were included in the territory called "Dalar-ADIAE", the western and n.w. were designated "Dalr-IEDA" and the name of the whole was "Endruim or Andruim" (Antrim) signifying the "habitation upon the waters".
In the reign of Queen Elizabeth I, "Dalar-ADIAE" was occasionally called "Mac Sorley Boy's Country".
According to the Irish annalists, Murdoch MacErch, chief of the Hibernian Dalar-ADIANS, early in the 4th century, by a series of conquests extended his dominions in the north of Antrim and the adjacent districts.
In the reign of Queen Elizabeth I, the English laid seige to Dunluce castle on the northern coast of Antrim, but was surrendered on honourable terms ; this fortress having been subsequently lost in 1585 was again given up to the English by Sorley Boy O'Donnell or MacDonnell, the proprietor of a great extent of the surrounding country, to whom it was returned in charge.
In part of the valley leading ato Lough Neagh is a round tower the site of the ancient monastery founded by ... "AODH".
Perhaps more information may be found in the history of McDonnell - Viscount Dunluce-Earl of Antrim.
