Earl of Glencairn

Earl of Glencairn was a title in the Peerage of Scotland. It was created in 1488 for Alexander Cunningham, 1st Lord Kilmaurs (created 1450). The name was taken from the parish of Glencairn in Dumfriesshire so named for the Cairn Waters which run through it.[1]

On the death of the fifteenth earl in 1796, there existing no original Letters Patent of the creation nor a given remainder in the various confirmations in title of previous earls the title became dormant

The earldom was claimed by Sir Adam Fergusson of Kilkerran, Bt., as heir of line of Alexander 10th, Earl of Glencairn and was opposed by Sir Walter Montgomery Cunningham of Corshill, Bt., as presumed heir male along with Lady Henriet Don, sister of the last earl, and wife of Sir Alexander Don of Newton Don, Roxburghshire. The House of Lords Committee of Privileges on 14 July 1797, chaired by the Lord Chancellor (Lord Rosslyn), in deciding the claim of the first-named, took a view unfavourable to all the claimants, and adjudged, that while Sir Adam Fergusson had shown himself to be the heir-general of Alexander, 10th Earl of Glencairn who died in 1670, he had not made out his right to the title. However, the decision was severely criticised by the jurist John Riddell in the 19th century and by Sir Iain Moncreiffe of that Ilk, Officer of Arms, in the 20th.
