Ordnance Survey Memoirs of Ireland, Vol 20: County Tyrone II, 1825, 1833-35, 1840

The Ordnance Survey Memoirs are a uniquely detailed source for the history of the northern half of Ireland immediately before the Great Famine. They were written in the 1830s to accompany the 6" Ordnance Survey maps, but with one exception were not published at the time. In this new edition they act as a nineteenth-century Domesday book and are essential to the understanding of the cultural heritage of our communities.

These Memoirs document the landscape and situation, buildings and antiquities, land-holdings and population, employment and livelihood of the parishes of Mid and East Tyrone.
