On 18 December 2013, Sir John Christopher Foggo Montgomery Cunninghame, Baronet of Corsehill, was recognized by Lord Lyon as Clan Chief after the chiefship had been vacant for over 200 years.

[2] Sir George Mackenzie states that the coat of arms allude to the office of Master of the King's Stables.

[2] The son of the Laird of Kilmaurs was Hervy de Cunningham who fought for Alexander III of Scotland at the Battle of Largs in 1263 against the Norse invaders.

[2] Sir William Cunningham of Kilmaurs was amongst the Scottish noblemen offered as a hostage to David II of Scotland's English captors in 1354.

[3] This was part of a century-long feud that had apparently started when the office of Baillie in Cuninghame, held by the Cunninghams, was awarded to the son of Lord Montgomerie on 31 January 1448-9.

[3] The two clans had been on opposing sides at the Battle of Sauchieburn, with Hugh Montgomery among the victorious rebels,[4] and Alexander Cunningham, 1st Earl of Glencairn slain with the defeated James III.

[4] In April 1586, Hugh Montgomery, 4th Earl of Eglinton, aged twenty-four, was traveling to Stirling to join the Court having been commanded to attend by the King, accompanied only by a few domestic servants.

[6] It seems that a plot to kill the Earl had been organized and the Lady or some say a servant girl who was also a Cunningham,[5] climbed to the battlements after the meal to hang out a white table napkin and thereby sprung the trap.

Robert also killed the Earl of Glencairn's brother the Commendator of Kilwinning Abbey, Alexander of Montgreenan, thought to have instigated Hugh's murder.

[8] The government of King James VI of Scotland eventually managed to make the chiefs of the two clans shake hands.

[2] Sir James Cunningham who married a daughter of the Earl of Glencairn was granted five thousand acres in County Donegal.

[2] During the Scottish Civil War, William Cunningham, 9th Earl of Glencairn supported Charles II of England.
