History
In the Plantation of Ulster by grant dated 29 April 1611, along with other lands, King James VI and I granted, inter alia, one poll of Dufferagh to Cormacke and Wony McGawran, but it is probable that the lands had been in the possession of the McGovern clan for several hundred years before this and it was just a Surrender and regrant confirming the existing title to the McGoverns. The said McGawrans were the children of a previous chief of the clan, Tomas Óg Mág Samhradháin who was elected in 1584. The lands are not shown on either the Plantation map of 1609 or the Down survey map of 1658 but would have been sub-divisions of Coologe townland at the time. The McGovern lands in Toberlyan Duffin were confiscated in the Cromwellian Act for the Settlement of Ireland 1652 and were distributed as follows- The 1652 Commonwealth Survey lists the name as Duffer and the proprietor as Shane McLaghlyne and the tenant as N. Pheely. In the Hearth Money Rolls compiled on 29 September 1663 there were two Hearth Tax payers in Dustin- William Smith and Shane McBrian. A grant dated 30 January 1668 from King Charles II to James Thornton included one pole in Duffin. In the 18th century Toberlyan Duffin came into the possession of the Hinds family. Walter Hinds of Corrakane left a will dated 5 Aug 1777 and proved on 18 July 1778. His estate was large and he named eight beneficiaries, including Martha Hinds, Ralph Hinds, Walter Hinds, John Hinds, William Hinds, Thomas Hinds, Anne Hinds and Mary Clarke. He left Toberlyan Duffin to his son Ralph as follows- To Ralph Hinds, his eldest son, the lands of Toberlion, Meelick and Duffin and the responsibility to pay his brother John an annual income of £40. Also to Ralph, and to his heirs forever, the lands of Nedd and Carnagee, and £1000 to be paid out of his father's effects together with two score of the best bullocks on the lands which he is to enjoy after his father's decease. A marriage settlement dated 3 February 1784 contained, inter alia, the part of Toberlion called Duffin and Meltea, otherwise Mellick. The will of Ralph Hinds dated 15 April 1794 and proved on 10 May 1794 included, inter alia, Toberlion, Meelick and Duffin in the County of Cavan. The 1790 Cavan Carvaghs list spells the name as Duffin. The Tithe Applotment Books for 1827 list forty eight tithepayers in the townland. The 1836 Ordnance Survey Namebooks state- The townland is bounded on the East by a large stream, and near the centre of the townland there is a beautiful spring from whence a stream proceeds, called by the inhabitants Tubberline Well The Toberlyan Duffin Valuation Office Field books are available for November 1839. In 1855 a local landowner in the townland, Charlotte Hinds, was murdered. Griffith's Valuation of 1857 lists nineteen landholders in the townland. On 17 March 1871 a rent-charge on the land belonging to the Hinds family was sold by the Landed Estates Court, including on The part of Tubberlion called Driffin.
