 In 1626, the Lordship of Kintyre was reconstituted in favour of the Earl of Argyll and Dunaverty Castle was denoted as its principal messuage.Argyll bestowed the Lordship of Kintyre on James, his eldest son by his second marriage, who, in 1635, at Dunaverty, granted a charter of the Lordship to Viscount Dunluce, eldest son of Randal MacDonnell, 1st Earl of Antrim.The transfer was set aside by the Scottish Privy Council, no doubt on a complaint by Argyll's eldest son, the Marquis of Lorn, who had bitterly resented his father's bestowal of the Lordship on his younger half-brother.
