A collection of the surviving letters of Honora (Nano) Nagle (1718-1784), foundress of the Sisters of the Presentation of the Blessed Virgin Mary (PBVM). Nano Nagle brought the Ursuline congregation to Ireland, before founding the Presentations. This collection represents a digital reunification of the surviving letters. A cousin of Edmund Burke, Nano was a member of a prominent Catholic landowning family in Munster. The material is collated from three separate archival collections: the Presentation Sisters Congregational Archives, Cork (PSCA); the archives of the Presentation Convent, George's Hill, Dublin; and the Presentation Archives, San Francisco, USA. Within the PSCA, there are letters originally belonging to the Archives of the Ursuline Convent, Blackrock, Cork; these letters were gifted to the Irish Presentation Sisters on the occasion of the tercentenary of the birth of Nano Nagle (2018). There is also one letter that was gifted by the Presentation Convent, New Windsor, USA, on the occasion of the tercentenary. The digital collection comprises of seventeen manuscript letters; the letters are from Nano Nagle to Eleanor Fitzsimons (later Sr. Angela Fitzsimons), an Irish religious novice in Paris, and from Nano Nagle to Teresa Mulally, educator of the poor, in Dublin.
