Thanks to Susan’s note, I found this at St. Dunstan’s Priory, about Bede Griffiths, about whom I had not heard before, who they commemorate May 13 (my father’s birthday):

Bede Griffiths (17 December 1906 – 13 May 1993), born Alan Richard Griffiths and also known as Swami Dayananda (Bliss of Compassion), was a British-born Benedictine monk who lived in ashrams in South India. He was born at Walton-on-Thames, England and studied literature at Magdalen College, Oxford under professor and Christian apologist C. S. Lewis, who became a lifelong friend.
