Uppingham School Roll, 1824 to 1905. E. Stanford. 1906., p. 212. The regiment is given as "30th C. I. Horse", which may be referring to either the 38th Central India Horse or the 30th Lancers (Gordon's Horse). The Commonwealth War Graves Database has an entry for John's son, killed in action in 1917, who was serving attached to the 38th Central India Horse; this would seem to make it marginally more likely that his father was also in the 38th.
