Lordship and Barony of Hailes
The Lordship and Barony of Hailes is a Scottish feudal lordship.
Hailes is traditionally believed to have been founded by an Englishman, taken prisoner in the reign of David II of Scotland, who was rewarded with the grant of lands in East Lothian for having rescued the Earl of Dunbar and March from an attacking horse.
Patrick de Dunbar, 9th Earl of March granted the Barony of Hailes to Adam de Hepburn in 1343 ; Hew Gourlay of Beinstoun having earlier forfeited the lands. On 20 December 1451, James II, King of Scots, granted Sir Patrick Hepburn, 1st Lord Hailes, and his heirs and assignees, the lands of the Lordship of Hailes, including Hailes Castle, and other lands, to be incorporated into the free barony of Hailes. Sir Patrick Hepburn was created a peer of the Parliament of Scotland under the title Lord Hailes in 1453.
The Lordship and Barony of Hailes remained in the Hepburn family until 20 December 1567 when it was forfeited to the Parliament of Scotland by James Hepburn, 4th Earl of Bothwell. On 1 October 1594, it was granted to Sir Walter Scott, 1st Lord Scott of Buccleuch, remaining with the Scott family until around the time of the Cromwellian invasion of Scotland in 1650 when it came into the possession of the Earls of Winton. In 1692, the Lordship and Barony of Hailes was disponed by James Melville of Halhill to Sir David Dalrymple, advocate and remained in the Dalrymple family until 1876 when it was transferred to A.J. Balfour.
The caput baronium of the Lordship and Barony of Hailes is Hailes Castle.
