Cecile O'Rahilly

Cecile O'Rahilly (; 17 December 1894 in Listowel, County Kerry, Ireland – 2 May 1980 in Dublin, Ireland) was a scholar of the Celtic languages. She is best known for her editions/translations of the various recensions of the Ulster Cycle epic saga Táin Bó Cúailnge.

Early years and education O'Rahilly was born in Listowel, County Kerry, Ireland to Thomas Francis Rahilly of Ballylongford, County Kerry and Julia Mary Rahilly (née Curry) of Glin, County Limerick. She was the eleventh of her parents' thirteen surviving children. Her older brother was the scholar T. F. O'Rahilly.

She received her primary education at the local national school in Listowel, before attending the Presentation Convent, also in Listowel. By 1906 after being widowed seven years previously, her mother moved the family to Dublin, where they lived at 66 Botanic Road, Glasnevin. O'Rahilly continued her education at the Dominican College in Eccles Street.

She received a BA with double first-class honours in Celtic Studies and French from University College Dublin in 1915, and, having won a Travelling Scholarship in Celtic Studies, she moved to Bangor in north Wales and studied under Ifor Williams and John Morris-Jones. She received an MA from the University College of North Wales in 1919. Their great-grand uncle was the noted Irish philologist and antiquary Eugene O'Curry. Their first cousin was Michael O'Rahilly (better known as The O'Rahilly) who was one of the founding members of the Irish Volunteers and died in the Easter Rising.

She never married, but lived with her companion Myfanwy Williams at 17 Raglan Road in Ballsbridge, after moving to Dublin in 1951. She had been sick for much of her life, and in her later years began to lose her sight. After a long illness, she died on 2 May 1980. She was buried in Glasnevin Cemetery.
