Thanks Ros! James Darch is a bit of a mystery man, eg. I haven't been able to find any suitable fit for him in England's BMD (perhaps he was just travelling through). He's immortalised in The Advertiser announcement 14th November 1892 of his step-son's wedding to Jean Darch, and in a lost-and-found ad he inserted in the same newspaper on 11th June 1891. He left South Australia for Cape Town supposedly in 1893, but I think it was in 1895. He died in Bulawayo, Rhodesia, in 1906.
