Introduction to the Coopershill Papers
The Coopershill archive runs from 1676 to 1974 and occupies 52 PRONI boxes. Almost all of it remains in family possession at Coopershill, Riverstown, near Collooney, Co. Sligo, the exceptions being the material relating to the Cooper family's estates in Cos Fermanagh and Tyrone, some mainly political papers of their cousins, the O'Haras of Annaghmore, Collooney, Co. Sligo, up to around 1830, some odds and ends relating to emigration to North America, and some other material of more than Co. Sligo local interest.
The originals of D4031 have been closed on preservation grounds, but the material is available on microfilm (MIC603). The PRONI list covers the entire archive, because the relatively small quantity of material deposited in PRONI cannot be properly understood and evaluated outside the context of the archive as a whole.
