I have traced my great-great-grandfather to be William Carl August Schultz, born circa Feb 1854 in Germany and moved to South Africa where he married Emmelina Christina Schultz (Nee Schultz). William was a farmer, so possibly was one of the agriculturalists who moved to South Africa from Germany in the 1800's. They had 8 children:
Agnes Munro William Edward Victor Myrtle Emely Rachael Ilva May Maybel
His name as I have written it is most certainly Anglicized, and he was probably born Wilhelm Karl August Schultz. His death papers show his wife did not know the names of any of his parents, only that he was born in Germany.
