Derrycassan

Derrycassan (from Irish: Doire an Cásain meaning either the "Path through the Oakwood" or "Cassan's Oakwood" (Cassan being an early Irish form of the present name Cassidy) is a townland in the civil parish of Templeport, County Cavan, Ireland. It lies in the Roman Catholic parish of Templeport and barony of Tullyhaw.

Derrycassan is bounded on the north by Kilnavert and Corran townlands, on the west by Camagh, Sruhagh and Gorteen, Templeport townlands, on the south by Derryniggin in County Leitrim and Burren townland and on the east by Coologe and Toberlyan townlands. Its chief geographical features are Coologe Lake, Derrycassan Lake and Camagh Lough. Derrycassan is traversed by a public road and several rural lanes.

The townland covers 498 statute acres.

The earliest surviving mention of the townland name is Doire Casáin, which appears in an interesting list of the rents due to the McGovern Chief, Maghnus 'Ruadh' Mág Samhradháin about 1400 A.D. It reads as follows:

This is the portion of Doire Casáin- 18 kegs of butter and 8 cakes and half a beef at Christmas and a sheep in autumn and a sheep in summer and two kegs of butter in winter and 8 kegs of meal and as much again in autumn and a keg of butter for Mayday and a gallon of butter for his ploughman in summer.

From this list we see that in 1400 the main type of farming carried on in Derrycassan was milk and beef cattle together with sheep.
