Sorley Boy is mentioned in "A Topographical Dictionary of Ireland" (written c.1836) under the parish of DUNLUCE, co. Antrim, Ulster, Ireland, page 585 vol.I. MacQuillan suffered the Scots around him to increase in strength till at length they expelled him from all his posssessions and Sorley Boy, brother of James MacDonnell, having obtained possession of the district called the Glynnes, made himself master also of this place.But Sir John Perrot, the English lord-deputy drove him from the castle in which he placed Sir Peter Carey whom he thought to be a man of the English pale, as governor, with a garrison of 14 soldiers.In 1585 Sir Peter, who was in reality one of the Carews of the north, brought around him some of his own country and kindred, and unknown to the deputy discharged the English soldiers, etc. The lord-deputy despatched to the assult of the castle an officer named Merriman who slew the 2 sons of James McDonnell, and Alexander, the son of Sorley was garrassed abd ge syrrebdered DUNLUCE and repaired to Dublin to make his submission which was accepted and on the condition of his fielity to the English crown he received a regrant of all his possessions, with the government of DUNLUCE CASTLE.This family was afterwards ennobled by the title of Earl of Antrim, and in 1642 Gen. Monroe, commander of the Scottish army in Ulster, with a party of his forces, paid a friendly visit to the Earl, by whom he was hospitably received; but at the conclusion of the entertainment Munroe gave the signal to his armed followers, who instantly made the Earl prisoner and seized the castle.
(Somewhere I believe I read that the name Sorley was S'Orley, changed to Auley orMcAulay changed to McConnelly, changed to McConnell; and the name McDonnell changed to McConnell which changed to Connell which changed to Campbell in Scotland.) This is interesting because it connects the Archibald Adair with the name Campbell, Dean of the Isles (Ireland) whom he worked under before being Bishop of Raphoe, etc. May be the connection between William from Kildare who named himself Adare and Sorley Boy.
