Here is information about Sheet 56:
This Inch to the Mile map covers areas of Counties Cavan, Fermanagh and Leitrim. Coverage stretches from Lough Nilly southward to Lough Allen, and from Killadiskert eastward to Swanlinbar.
The only substantial settlement on the map is Swanlinbar. Other features include a stretch of the Sligo Leitrim & Northern Counties Railway, Cuilcagh, Dowra, Benbrack, Bencroy, Florence Court, Brackley Lake.
On the reverse we include a detailed map of Swanlinbar itself, with individual houses neatly delineated, mostly alongside the main (only) street; other features include churches, Trivia House, Constabulary Barracks, Long Bridge, St Mary's Presbytery.
It is not possible to list the many hamlets, farmsteads and other topographical features shown on these maps. However, you may find it useful if we list the towns and principal villages or church parishes that are included on this map. Links are given for those for which detailed large-scale maps are also available.
