My great great grandfather was Edmund Daniel Hamer, and I suspect that he was born in the UK (but not sure where). He married Annie Keen who was born in Illmer/Aylesbury, Buckinghamshire (b 1864). They settled in Port Elizabeth, South Africa and had two sons, one of which was my great grandfather, Edmund Charles Hamer. EC Hamer had a number of daughters and one son, my grandfather, Charles William Hamer.
Do you think there is any connection with your family?
