ABERDOUR, a small town in Fife-shire, Scotland, on the frith of Forth, about ten miles N. W. of Edinburgh. In old times it belonged to the Viponts; in 1126 it was transferred to the Mortimers by marriage, and afterwards to the Douglasses. William, lord of Liddesdale, furnished the Flower of chivalry, in the reign of David II. by charter conveyed it to James Douglas, ancestor of the present noble owner the Earl of Morton. The monks of Inchcolm had a grant for a burial-place here from Allan de Mortimer, in the reign of Alexander III. The nuns, usually styled the poor Clares, had a convent at this place.
