of the third Lord Kennedy, Janet Kennedy who had a son by James IV of Scotland, as part of the possession of the earldom of Moray. The Moray Kennedys became a sept of the Clan Cameron. 17th century and Civil War In 1601 the Kennedy Earls of Cassilis were involved in a feud against their relations, the Kennedy Lairds of Bargany. The Earls of Cassillis were supported by the Clan Fergusson and the Laird of Bargany was killed. From 1649 to 1651, John Kennedy, 6th Earl of Cassilis was Lord Justice General of Scotland and a zealous Protestant. He and his son, the seventh Earl, were both firm supporters of Parliament during the Civil War. The Justice General also sat in Oliver Cromwell's House of Lords. The Kennedys suffered for their beliefs but their estates remained largely intact. The Kennedy of Kermuck branch of the clan were hereditary constables of Aberdeen from at least 1413.

The earldom of Cassillis now passed to a cousin, Archibald Kennedy, a captain in the royal navy, whose father, Archibald Kennedy (died 1763), had migrated to America in 1722 and had become collector of customs in New York. His son, the 11th earl, had estates in New Jersey and married an American heiress; in 1765 he was said to own more houses in New York than any one else. He died in London on 30 December 1794, and was succeeded by his son Archibald (1770–1846), who was created Baron Ailsa in 1806 and marquess of Ailsa in 1831. His great-grandson Archibald (born
