GLENCAIRN, EARLS OF. The 1st earl of Glencairn in the Scottish peerage was ALEXANDER CUNNINGHAM (d. 1488), a son of Sir Robert Cunningham of Kilmaurs in Ayrshire. Made a lord of the Scottish parliament as Lord Kilmaurs not later than 1469, Cunningham was created earl of Glencairn in 1488; and a few weeks later he was killed at the battle of Sauchieburn whilst fighting for King James III. against his rebellious son, afterwards James IV. His son and successor, ROBERT (d. c. 1490), was deprived of his earldom by James IV., but before 1505 this had been revived in favour of Robert's son, CUTHBERT (d. c. 1540), who became 3rd earl of Glencairn, and whose son WILLIAM (c. 1490-1547) was the 4th earl. This noble, an early adherent of the Reformation, was during his public life frequently in the pay and service of England.
