Find Ancestors

Michael McCann Hi I am trying to find or track my relations on my father's side . My father's name was Gerard Hugh McCann , he was born near Drumadarragh , Northern Ireland in 1913 .He left Ireland to teach near Worcester, England and later left England to go to South Africa. He moved to Zambia (Northern Rhodesia) where he married my mother , Gladys Darlison. They had two children, Sheena and myself ,Michael, sadly my father passed away in 1962 so I never knew him as I was not two years old then .His father's name was Francis McCann , a farmer, and his mother , Catherine nee McKenna , was a doctor , I believe he had two sisters , one a nurse and the other a shopkeeper. Any help would be gratefully received as I have no recollection of my father and my mother has very few documents relating to hlm .
