Please assist in advising how I find a naturalisation certificate for my grandfather in South Africa. 

he settled in Natal. I have searched all the Natal archives online and well as the South African archives. 

who would have a copy of it? I have no idea even if the year. 

is there a way to search government gazettes to find the Naturalisation? 

Any advice or assistance most appreciated.
