I am trying to trace my family tree. My father John Alan Hibbert was born near Doncaster in the 1940's. He imigrated to South Africa in the late 1960's after marrying my mother Patricia Ann Barton. I beleive my grandfather died 18 yrs ago and my grandmother died when my dad was 2yrs old. My dad's step mother is Flo and he has two step brothers David and Roger. I would be grateful for any assistance. Thank you.
