[2] His exact date of birth is unknown, but he was 4 months old when he arrived with his family in England in March 1902.
[3] Miles was a mercantile assistant in Port Said, Egypt, in the 1920s,[4] and, prior to ordination, a missionary in Mauritius.
[5] He trained for ordination at St Boniface College, Warminster, and was ordained deacon in 1932 and priest in 1933.
[10] As assistant bishop, he established himself in Tamatave, with the intention that this would be a diocesan see on division of the Diocese of Madagascar, although this did not take place until three decades later, in 1969.
[11][12] In 1940 Gerald Vernon became Bishop of Madagsacar, but, due to the Second World War and the Fall of France, was unable to get to his diocese, which, in his absence, was managed by Miles and the native clergy.
