I need help. I have been down a number of avenues and hit brickwalls. I am based in the UK. I amd trying to find a death certificate of Ernest Cort Dunn who was born in the UK but set uphome in Rhodesia/Zambia. He moved to Broken Hill (Kabwe) in the early 60's, where I believe he died. He was in the Royal Engineers. I have found him and his wife Doreen Isabelle coming to the UK from Jo'burg in 1954 presumeably to visit family. I have a baptism of a son born 1925 (ancestry24) but I have many gaps which I have been unable to fill. Thank you
