In the early to mid 1900's, several of my ancestors moved from South Africa to the Copper Belt in Northern Rhodesia (now Zambia). I'm sure they are all buried in or near Broken Hill. How do I get death certificates and could anyone visit the cemetary to take photos of tombstones with the names Povall and Williams on. I think they were farmers so presume they could be buried on their farms. How does one get info from the Zambian Government?
