AUCHTERLONY, the surname of an ancient Forfarshire family, who formerly possessed the barony of Kelly in the parish of Arbirlot. Rather more than two miles west of Arbroath, on the edge of a precipice, at the side of the river Elliot, are the ruins of the castle of Keily, otherwise Auchterlony. The first proprietor of Kelly noticed in history was Roger de Moubray, an adherent of Edward the First of England, who, in the distribution of the estates of the Scottish barons opposed to his pretensions as lord paramount of Scotland, bestowed these lands upon him. In 1321, Moubray was declared a traitor, and his barony forfeited. Kelly was then conferred on the steward of Scotland, the son-in-law of Bruce. In the reign of Robert the Second we find Alexander Auchterlony designed of Kelly. This Alexander Auchterlony married Janet, daughter of Sir William Maule of Panmure, knight, and got with her the lands of Greenford, in the same parish. It would seem that the barony of Kelly had passed from him or his successor, for it is recorded that William Auchterlony acquired Kelly in the year 1444, and from that date till 1630 it remained in possession of the family of Auchterlony. At the Reformation the chief of the Auchterlonies, according to tradition, was very active in the destruction of the abbey of Arbroath. Being indebted to the abbey steward, at the head of three hundred men he attacked the abbey, and setting fire to it, burnt all evidence of a claim against him. Among the witnesses to a charter of a donation to the hospital at Dundee, dated 2d May 1587, appears the name of David Auchterlony dom, de Kelly, who is supposed to have been either the incendiary or his son. Kelly now belongs to Lord Paumure, and the ancient family of Auchterlony is represented by John Auchterlony of Guynd, Esq— See OCHTERLONY.
