Many thanks for this lead. Although it hasn't taken me directly to what I am looking for, it has given me a fresh start. Capt. B.S.Greville's family were living in Pietermaritzberg at the same time that the 2nd Batallion Royal Fusiliers were encamped there around 1908-9. My (distant) cousin, Lt. Belgrave Ninnis, was a friend of the family and kept in touch until he went to the Antarctic in 1911 where he lost his life. I have wondered what became of Greville's younger daughter, and if there are any family recollections of this period.
