A Co Cavan nun who was also a midwife delivered Pope Francis as a baby at his family home in Argentina in 1936.
An expert in the world of Irish missionaries has made the discovery.
Matt Moran, who wrote The Legacy of Irish Missionaries Lives On, has traced the origins of the Cavan nun who helped Pope Francis in his earliest days to Crosserlough.
Sr Oliva Maria, formerly Susan Cusack, trained as a nurse and midwife in Paris with the Little Sisters of the Assumption from 1909 onwards. The order of the Little Sisters of the Assumption were founded in France in 1865.
Susan Cusack, a daughter of a small farmer left Crosserlough aged 20 years of age to train, little did she know on December 17th 1936 she would deliver and care for a future pontiff, Pope Francis.
Mr Moran who is a former chairman of Misean Cara, a charity which supports missionaries has been speaking to Ronan Gargan and says he was fascinated to discover her life-story.
