Baron of Glengarnock

In the 12th and 13th centuries, the lands here were held for the King by the De Morville family, hereditary Great Constables of Scotland.

Reginald was the second son of Edward Cunningham of Kilmaurs and Mary, daughter of the High Steward of Scotland.

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 1701, he adorned the laird's loft of the fifteenth century parish church of Kilbirnie with eighteen shields of the Lindsay lineage.

In 1749, George fell heir to the titles and estates of John, 20th Earl of Crawford and 4th Lord Lindsay and settled with his wife Jean Hamilton at Kilbirnie Castle.

Kilbirnie Castle was largely destroyed by fire in 1757, forcing George him to move to his property at Crawford Priory in Fife.

Upon the death of his father in 1781, his eldest son George, a major-general in the British Army inherited the lands and titles.

Upon the death of George in 1808, the Crawford-Lindsay estates, along with the feudal titles which were then tied to the land, including the Barony of Glengarnock, went to Lady Mary Lindsay Crawford, and subsequently to the Earls of Glasgow.

The Barony of Glengarnock thereafter remained in the line of the Earls of Glasgow until eventual disposition to the MacGregors of Rannoch.
