Derryart is a townland in the civil parish of Tomregan, barony of Knockninny, County Fermanagh, Northern Ireland.
Its chief geographical features are the Duvoge River and a drumlin hill reaching to 60 metres above sea-level.
The map for Knockninny barony stops on the east bank of the stream entering the Woodford river between the townlands of Derryhooly and Corry townlands,[2][3] while the Tullyhaw barony map stops where the Irish border is now,[4][5] thus omitting that part of Tomregan parish which lies in County Fermanagh.
A grant was made to Thomas Monepeny on 15 October 1610 of the Manor of Aghalane, which included one tate of Derarke.
[8] An Inquisition held at Castlecoote on 5 November 1629 stated that David Creighton owned, inter alia, 1 tate of Derarke.
[10] The Tithe Applotment Books for 1827 (which spells it as Derralt) list the following tithepayers in the townland- Shearson, Chambers, Graves.
