Carrowmore, County Cavan is a townland in the Parish of Tomregan, Barony of Tullyhaw, County Cavan, Ireland.
The townland name is an anglicisation of the Gaelic placename "Ceathrú Mhór" which means ‘The Great Quarter’. It derives its name from the large size of the townland which in medieval times comprised a quarter of the ballybethagh of Calvagh, as it originally consisted of the present-day townlands of Carrowmore, Mullanacre Lower, Mullanacre Upper and Moher, a total of 2,066 statute acres. The oldest surviving mention of the name is in the 1609 Ulster Plantation grant where it is spelled ‘Carraghmore’.
It is bounded on the north by Legavreagra and Aghnacally townlands and the international border with Fermanagh and Northern Ireland, on the east by Snugborough and Derryginny townlands, on the south by Lecharrownahone townland and on the west by Mullanacre Upper, Mullanacre Lower & Drumane townlands. Its chief geographical features are Loughan Macmartin mountain lake, the Crooked River (Ireland), some mountain streams, forestry plantations and Slieve Rushen mountain, on whose southern slope it lies, reaching an altitude of 1,294 feet (394 m) above sea-level. It forms part of the Slieve Rushen Bog Natural Heritage Area [4]
The townland is traversed by the Bawnboy Road, the Laher Road, Carrowmore Lane and other minor lanes.
The townland covers 981 statute acres, including 1-acre (4,000 m2) of water.
It formed part of the Manor of Calva which was granted to Walter Talbot in 1610 as part of the Plantation of Ulster. The Hearth Money Rolls of 1664 list the occupiers of Carrowmore as John O’Flynn, Tirle Maguire, Philip Brady, Edmond Reilly, Donoghy O’Finnegan, William Borke, Cormucke O’Dany, Tirlagh O’Catany, Shane McKernan, Shane McLanery and Philip O’Reilly.
