History
In the Plantation of Ulster by grant dated 24 February 1614, King James VI and I granted, inter alia, one pole of Dirriconosy to Phelim McHugh O'Reyly, Bryan McHugh O'Reyly and Cahir McHugh O'Reyly, the sons of Hugh Reyly, late of Ballaghaneo, County Cavan. Ballaghaneo is now the townland of Ballaghanea in Lurgan Parish, County Cavan, on the shores of Lough Ramor, so the O'Reillys were removed a long way from their home by the Plantation. Hugh Reyly was the great-grandnephew of the chief of the O'Reilly clan, Eoghan na Fésóige mac Seoain, who ruled East Breifne from 1418–1449. The O’Reilly lands in Derryconnessy were confiscated in the Cromwellian Act for the Settlement of Ireland 1652 and were distributed as follows- The 1652 Commonwealth Survey depicts the townland as Direcumisk with the proprietor being Captain Payne and the tenant as Daniell McConnell. A lease dated 31 January 1718 from Morley Saunders to John Enery of Bawnboy includes the lands of Derriconisey. A lease dated 10 December 1774 from William Crookshank to John Enery of Bawnboy includes the lands of Derryconessey. A further deed by John Enery dated 13 December 1774 includes the lands of Derryconesse otherwise Derryconessy. The 1790 Cavan Carvaghs list spells the name as Derryconnisy. A map of the townland drawn in 1813 is in the National Archives of Ireland, Beresford Estate Maps, depicts the townland as Derryhaunis and the proprietor as John Ennery. A lease dated 17 September 1816 John Enery of Bawnboy includes Derinyconesey otherwise Dereconocy. The Tithe Applotment Books for 1827 list eleven tithepayers in the townland. The Derryconnessy Valuation Office Field books are available for September 1839. In 1841 the population of the townland was 36, being 17 males and 19 females. There were five houses in the townland, all of which were inhabited. In 1851 the population of the townland was four, being 2 males and 2 females, the reduction being due to the Great Famine.

Antiquities
There are stones inscribed in Irish in the stream dividing the western part of Derryconnessy from Tonlegee townland. The 1930s Dúchas Folklore collection give the following accounts of a battle fought there- A battle was fought in Crocán na gCamps, Derryconnessy; Corlough. Co. Cavan. It is supposed to have been fought between the Gael and Danes. When the cavalry were coming to Crocán na gCamps they had a row and fought a battle. The fought in Tullyvella and Conspud. It is not known which side won the battle, but they are still supposed to fight, at certain times of the year at night, and it is thought to be a bad sign of disturbance when dead people come back to fight. There are Ogham stones at Crocán na gCampa.Long ago, when the early colonists came into this country, they had a big battle on the land now owned by Mr. Francis McGovern, Tonlagee, Corlough, Bawnboy, Co. Cavan. The field in which one army pitched their campaign is now called Cnocán na gCampa which means 'The little hill of the campus'. It is a pretty field with grass much greener than that in the neighbouring fields. Beside it, is the field where the battle was fought. It is a grey field covered with large stones which are said to be monuments to the men who fell in the battle and are buried under them. It is said that if the field was dug up, the bones of the dead would be found in it. A stream runs by the battle fields, and touches it on the two sides. The stream is almost choked up by big stones, and there are two stones among them, with old Irish writing on them. This is all the information that is available about the battle in this district. It is not known exactly what tribes had the battle, but it is known that it took place thousands of years ago. The fields are along the main road from Swanlinbar to Ballinamore. If the accounts of the battle are correct then the name on the 1813 map Derryhaunis could be the Irish Doire hAmhnais'' meaning 'The Oakwood of Combat'.
