I have a couple of groups that cover the period from the Boer War to World War II, but the pair shown here stands out because it is an unusual combination of medals.
Frederick Mayfield Sivil was born in Lincolnshire in about 1873. He was a schoolteacher who settled in Durban in about 1897. There he joined the naval militia unit, the Natal Naval Volunteers, which was mobilised at the outbreak of the Boer War. The NNV became part of the Naval Brigade, with some men taking part in the 'Relief of Ladysmith' and others in the 'Defence of Ladysmith'. Sivil was amongst the latter. He was discharged after the Ladysmith siege was lifted and returned to his life as a teacher.
It seems he was not to serve in uniform again and was not on active service in either the 1906 Natal Rebellion or World War I. However, in World War II he "served for at least two years in [a] voluntary organisation in South Africa" that benefitted the local war effort and thereby qualified for the South African Medal for War Service.
