Maurice Cashell was born in Tralee, County Kerry, on 14 September 1927. He was received into the Capuchin novitiate in Rochestown, County Cork, in 1944. He took Vianney as his religious name upon joining the Capuchin Franciscans. He completed his philosophical studies in University College Cork and his theological studies in Ard Mhuire Friary in County Donegal. He was ordained to the priesthood in October 1952. Following his ordination, he was sent to Rome and later to Louvain for further studies. Shortly after his return to Ireland, he was assigned to a special ministry in Beirut, Lebanon, in 1965. He was transferred to the American Vice-Province in 1970 and was initially posted to San Buenaventura Friary in San Francisco helping in retreat ministry. During this time, he successfully applied for the position of philosophy teacher at Sn Francisco State University. However, he died before he could take up this academic role. His death (due to an undiagnosed heart condition) occurred whilst he was giving a retreat to religious sisters in San Diego in California. He was buried in Holy Cross Catholic Cemetery in Colma, San Mateo County, California.
