It is interesting that he was a Major in the Madras Staff Corps,
because when I did the research for a Smith who had the same job.
modified.......John Smith, Major General, Bengal Staff Corps.
his mum was a Molison.[i don't know if that is similar]

I don't know if any of this is relevant, I can't follow whats going on.
