Ordnance Survey memoirs...

Discover your ancestors.

The memoirs were written descriptions intended to accompany the original Ordnance Survey maps, containing information that could not be fitted on to them. They are a unique source for the history of the northern half of Ireland before the Great Famine, as they document the landscape and situation, buildings and antiquities, land-holdings and population, employment and livelihoods of the parishes.

The surveyors recorded the habits of the people, their food, drink, dress and customs. Details of ruined churches, prehistoric monuments and standing stones were also included. The Ordnance Survey memoirs were published in 40 volumes by the Institute of Irish Studies at The Queen’s University of Belfast, with an additional index volume covering the entire series.
