Hi
thanks for that interesting info. My relative is 2nd from the left , back row in second photo. He is Robert Irving Johnston , Detective Head Constable and finger print expert. He formed the Natal Police shooting team in 1910 according to a retiral article in a newspaper. I have a copy of the newspaper article and an address to a leaving colleague which many of his colleagues signed however not the name you mention. His wife was Daisy Baines , Prima Donna and actress.
This was a most exciting journey of discovery from two photos I knew no one in originally- to discovering a whole new South African living branch of the family.Thanks to Roots chatters xx
