Find Ancestors

I would like to find my cousins : Barbara and Brenda White - daughters of William and Lillian (or Alice) White, who live near the Children's Hospital in Hackney Road, London. Barbara born about 1935, married Ernie Wilkinson approx. 1961 and had a daughter 'Bonnie'. Last known to be living in Aveley in the 1960's. Also Brenda, born about 1943, married name Porter lived in the Stamford Hill area and last seen waiting for a bus outside Liverpool Street Station around 1964. Also Raymond, son of Jack and Rose, now aged approx 53/54. Jack died in the 1950's and Rose possibly remarried, perhaps changing Raymond's name. Also John White, aged approx 60, son of John (known as Jack) and Lil, last known to be living in the South Ockendon area in the 1960's. My dad was Frederick George White, born 10.8.1905, died 19.11.78, son of William John and Isabella White (maiden name Copp born on 29.11.1874 and died 10.03.1948) and married on 16.04.1905 and lived at 51 Barnet Grove. Isabella's parents wereCharles and Mary (nee Chapman) who lived at 14 Hewlett Road, Bow. Can anyone match up any of these names in their tree please? Unfortunately I have no contact with any of my father's relatives now. Dad had another brother Ben, who had no children. Ben died in the 1980's. Unfortunately, I know nother more of my dad's family and would love to hear from anyone who knew the family who grew up in Bethnal Green.
