Find Ancestors

Hi all I'm trying to research my family tree but have hit a brick wall at a very early stage in my searching. My mother died 1980 in SHROPSHIRE. Her death certificate reads; EUNICE MARGO DUCE (formerly SMITH, formerly ANGELONI, Nee SMITH) she was known as Margo to everyone. She had brothers and sisters - who all lived in the south SHROPSHIRE area: WILLIAM (known as BILL); ERIC; IRIS; CICILY. Her parents were LILIAN and SYDNEY JACKSON from LUDLOW, SHROPSHIRE although Lilian had been married before to someone with the surname SMITH. Lilian - my grandmother - apparently is of Irish Romany blood from the CORK area where according to my mother I still have family! My father is ROY ANTHONY SMITH, who although he's still alive cannot remember very much. He was born in ST. MAWES, CORNWALL in approximately 1926. His parents died when he was quite young and he was moved to a family in SMETHWICK, WEST MIDLANDS in the early 1930's. I know this is a long shot but if anyone can try to fill in the missing gaps I would be extremely grateful. Thanks for reading this novel!!!!
