Find Ancestors

Trying to find relatives of my father Trevor Cooper. He had four brothers. Ken,Les,Dudley & Ron (who emigrated to Canada) and two sisters, Naomi & Adelaide both of whom are dead.Relatives used to live in Bridgend,Glamorgan.My father was married twice. He had a daughter by his first marriage, Sonia who I beleive also emigrated to Canada with her husband so I so not know her surname.His mother lived in Finchley, London and was called Hannah. She died a good few years ago.I do not know his fathers name. My father moved to Smethwick from London and was a milkman, which is how he met my mother. He then took myself and my brother to West Heath, Cofton Hacket, Birmingham where he lived with my mother till his death in 1964. He worked at British Leyland.I would so love to hear from anyone who thinks they may know where any of my relatives on my fathers side may be now.Wives of the brothers were called, Rose (Ken) Emily (Dudley) Jean (Ron) I cannot remember Les's wifes name.We visited the relatives in Wales once when I was about 5, so a good few years ago.(47 actually).
