The Kennedy baronetcy, of Culzean in the County of Ayr, was created in the Baronetage of Nova Scotia on 8 December 1682 for Archibald Kennedy. He was the great-grandson of Sir Thomas Kennedy, Master of Cassilis, younger son of Gilbert Kennedy, 3rd Earl of Cassillis. The 4th Baronet succeeded to the earldom of Cassillis in 1759. [1]
Susanna, Countess of Eglinton, daughter of the 1st Baronet, was a celebrated beauty and literary patron.
The baronetcy remained a subsidiary title of the earldom, until the baronetcy became extinct in 1792. See Marquess of Ailsa for further history of the baronetcy.
