History
From medieval times up to the early 1600s, the land belonged to the McKiernan Clan. The 1609 Plantation of Ulster Map depicts the townland as Keylagh. A grant of 1610 spells the name as Keylagh. A lease of 1611 spells the name as Keylough. An inquisition of 1629 spells the name as Keylagh. The 1652 Commonwealth Survey spells it as Killagh. In the Plantation of Ulster King James VI and I by grant dated 27 June 1610, granted the Manor of Keylagh, which included one poll in Keylagh, to John Achmootie, a Scottish Groom of the Bedchamber. His brother Alexander Achmootie was granted the neighbouring Manor of Dromheada. On 16 August 1610 John Aghmootie sold his lands in Tullyhunco to James Craig. On 1 May 1611 James Craig leased, inter alia, 1 poll of Keylough to McKernan. On 29 July 1611 Arthur Chichester, 1st Baron Chichester and others reported that John Auchmothy and Alexander Auchmothye have not appeared at the lands awarded to them. James Craige is their deputy for five years, who has brought 4 artificers of divers sorts with their wives and families and 2 other servants. Stone raised for building a mill and trees felled, a walled house with a smith's forge built, 4 horses and mares upon the grounds with competent arms. An Inquisition held at Ballyconnell on 2 November 1629 stated that the poll of Keylagh contained seven sub-divisions named Toynelodabraranie, Knockelinahan, Gortinagripp, Moneneweek, Rassorin, Townelubban and Monynshellagagh. Sir James Craig died in the siege of Croaghan Castle on 8 April 1642. His land was inherited by his brother John Craig of Craig Castle, County Cavan and of Craigston, County Leitrim, who was chief doctor to both King James I and Charles I. The 1652 Commonwealth Survey states the owner was Lady Craig. A grant dated 30 January 1668 from King Charles II of England to James Thornton included a 1/2 poll containing 124 acres 1 rood and 8 perches in Kealagh. The 1790 Cavan Carvaghs list spells the townland name as Kilagh. The 1825 Tithe Applotment Books list nine tithepayers in the townland. The Keilagh Valuation Office books are available for 1838. Griffith's Valuation of 1857 lists ten landholders in the townland. On 13 November 1851 the following decision was made by the Incumbered Estates Court- The Chief Commissioner sat in the Court, Henrietta-street, Dublin, to-day, for the purpose of selling incumbered property. In the matter of the estates of Williams James Thomas GALBRAITH, owner. Ex parte Morgan CROFTON, petitioner.
