I am relying on John Steward's gravestone 08/19/01 in the Colonial Cemetery for the correct spelling of his surname. His age at death was 55. His obituary notice giving 22 January 1877 in the Hong Kong Daily Press, which matches that on his gravestone, gives his name as John Stewart. Carl Smith switches backwards and forwards between "Stewart" and "Steward". The first entry in the Carl Smith cards gives "J. Stewart as Ist Officer on the Schooner, "Royalist" in 1849. In the Jury lists for 1871, 1875 and 1876 John Steward is given as a boarding house keeper in Queen's Road - but which boarding house? John "Stewart" is also given as a licensed victualler in Queen's Road. Abdool Razak Madar was his executor. My great-grandfather, John Olson is described as a "servant" of Stewart and Lumbah in 1867, presumably meaning their employee. The Carl Smith card for Lumbah 00156397GIF states that he appointed John Steward of Victoria, licensed victualler as his executor in 1865, so it does seem as if this is the same man.
[message for David: I haven't been able to fill in the correct dates of birth and death under the new system. Winding back two centuries from 2022 to 1822 doesn't seem to work. It would be easier just to type in the date as before]
