Sir Errol Manners K.B.E (1883–1953) was a distinguished Royal Navy admiral and author on theology and British Israelism. He completed fifty-two ocean convoys during the Second World War, including ONM 249 which consisted of 153 ships. He wrote segments of research in a lengthy book titled Bible Research published in 1946, which quickly became popular among proponents of British Israelism for its chapter titled "The Hebrew origin of English. Israelite heraldry in Anglo-Saxon countries".
He and his three sons, Rodney, John and Sherard, all served as naval officers in World War II. John was Lieutenant Commander aboard HMS Viceroy when it sank U-1274 on 16 April 1945.
