The Barony of Glengarnock is a Scottish feudal barony in the county of Ayrshire in Scotland.
The Crown Charter proscribes the Barony of Glengarnock baronial lands as follows:
“The lands and barony of Glengarnock, the dominical lands of Glengarnock, the lands of Blackburn, Blackhill, Birkhill and Barhill, and marshes and waters called Paddockholm, the lands of Bridgeend, Henyholm, Pewlands and Burnside, Bashaw, Baillieston and Damathland, Kirklands of Kilbirnie, the Mill of Glengarnock and Multures of the same, the loch called Loch Tankard, the lands of Burns, Auchinhove, Denholm, Loch Rigg and Lochend, the six shilling and eight penny lands of Corse and forty shilling lands of Cherrylands, all lying in the Parishes of Kilburnie and County of Ayr”
In the 12th and 13th centuries, the lands here were held for the King by the De Morville family, hereditary Great Constables of Scotland. The barony was anciently in the possession of a family of the name of Riddell, supposed to have been descended from the Riddells of Teviotdale.
Reginald Cunningham. The earliest proprietor of the Glengarnock barony is believed to be Reginald Cunningham, of a cadet branch of the Cunninghams of Glencairn. Reginald was the second son of Edward Cunningham of Kilmaurs and Mary, daughter of the High Steward of Scotland. Reginald married Jonet Riddell, the daughter and heiress of Riddell of Glengarnock sometime around the middle of the thirteenth century.
William Cunningham of Glengarnock. In 1547, William Cunningham of Glengarnock is recorded as having been killed at the Battle of Pinkie.
Sir James Cunningham. William Dobie records that Sir James Cunningham in 1609 assigned the 'Lands of Glengarnock' to his creditors and went to Ireland where he managed the 12,000 acres of land that King James VI had granted him. The estate was sold by the creditors to William Cunningham of Quarrelston.
William Cunningham of Quarrelston. In 1654, William Cunningham of Quarrelston alienated the property to Richard Cunningham, eldest son of William Cunningham, a Writer to the Signet, member of a cadet branch of the Cunningham of Ashinyards family.
Richard Cunningham. Richard Cunningham was a staunch supporter of the House of Stuart and as such rallied to the Royal Standard during the Wars of the Three Kingdoms, 1638-1651. In 1648, Richard took part in the Royalist invasion of England only to be defeated at the Battle of Preston (1648), and again in 1651 he rode south to be beaten by the Cromwellian army at the Battle of Worcester. Richard avoided capture and returned home to Glengarnock where he died and was buried in the Glengarnock Aisle of Kilbirnie Kirk.
