Ayrshire
The chief interests in Ayrshire were in the Campbells, earls of Loudoun, its hereditary sheriffs, and the Montgomeries, earls of Eglintoun. From 1710 to 1727 the seat was held by John Montgomerie, first cousin of the 9th Earl of Eglintoun, and from 1727 to 1741 by James Campbell, whose father was the 2nd Earl of Loudoun and whose mother was the daughter of the 7th Earl of Eglintoun.
