Could you possibly look for the names of John James Hart, born 4 Aug 1852, and his father, William Hart, birthdate unknown. John James is my great grandfather, and his early life, before his marriage in 1879 in Rangoon, is mostly a mystery. I do recall my late mother saying that her grandfather "was in Afghanistan", but she could have been referring to her great grandfather, William Hart.
Many thanks, BritCanadian
