1829–1899
Known as the "Nun of Kenmare," she was a vivid and sometimes controversial voice in 19th-century Ireland, writing widely on history, religion, and social conditions. Her life moved across denominations, public causes, and religious communities, giving her story an unusual amount of drama and range.

by Mary Francis Cusack
Born Margaret Anna Cusack in 1829, she later took the religious name Mary Francis Clare Cusack. Raised in the Anglican tradition, she became a Roman Catholic in adulthood and joined the Poor Clares, eventually becoming widely known in Ireland as the "Nun of Kenmare." She wrote prolifically, producing books on Irish history, religious life, and the hardships faced by poor tenants and emigrants.
Cusack was not only an author but also a public campaigner. Her writing and charitable work brought her a large readership, and she became especially well known for speaking plainly about poverty and injustice. She later founded the Sisters of St. Joseph of Peace, showing how seriously she took the connection between faith and practical social action.
Her later years were marked by conflict and change. After leaving the community she had founded, she returned to Anglicanism, the faith of her youth, and died in 1899. That complicated journey helps explain why her books still attract interest: they come from someone who lived through deep personal, religious, and social upheaval.
