Find Ancestors

I am trying to find any family of Robert Cecil Hives - born Chesterfield 16/02/1916 and married Margaret Pugh (b. Chesterfield 10/05/1920) on 29/08/1942. Robert (also known as Dick after the cricketer) had a sister called Doris but the family separated after the death of Robert and Doris's mother while giving birth. Robert's father was John Cecil Hives who died on 15/03/1951 I believe. I have no information about Robert's mother, however I do know that Robert's father John was the son of Joseph Cecil Hives (b. 27/08/1888) and Olive Haslam (b 1894 and died of TB at the age of 26 on 03/03/1920). The wedding of Joseph and Olive, 03/04/1915, was witnessed by John Edward Hives who I assume to be a family member. Joseph Cecil had many children, as many a 9 I am led to believe. Joseph's father was George Hives. Robert had two children - Derek (21/01/1948) and Philip (23/03/1949) and sadly only Philip, my father, survives: Robert died of stomach cancer in September 1996 and Margaret (nee Pugh) died in Apr/May 1997 swiftly followed by Derek of a heart attack in December 1997. Any information, particularly about Doris and her children (I know she had several) would be greatly appreciated.
