Dr Ralph emigrated to Canada, around 1902, and in 1919 a Mr H W Forster, of Albaston, Callington wrote to the press: “After being in the Army I was sent to work under the Bishop of Saskatchewan, Canada, among the soldier settlers in his Diocese. In 1917 I was posted to the Blain Lake district of Saskatchewan. Soon after arriving there I formed a close friendship with Dr Ralph which lasted until Dr Ralph’s death on his “Craigmore” estate, overlooking the South Saskatchewan River in 1923. Dr Ralph loved nature and the free life of the prairie and was happy out with horses, haymaking, preparing for the wheat crop, or saving the wheat; or even on Sundays when driving over the prairie to conduct a service at some little church, for he was also Minister of the Congregational Church, often preaching to a congregation of Canadians, English, German and Russian settlers, all known to him by his wonderful gift of love and sympathy to all. All classes and creeds came to him for help and advice, which he was always ready to give.
