1894 Born England (from RIC roll) But apart from 1911 census, saying he was born in London, there is nothing else on him. No such birth registered, nor can I find marriage of his mother, nor the family in 1901 census. However....
1894 Born Westminster, London as Hugh Cecil Banfield illegitimate son of Elizabeth Jane Banfield, born Redruth 1857. In 1913 Hugh J C Gibsone marries Elizabeth Jane Banfield. This is a few months after the death of H J C's father and it would appear that he waited till his parents died before he married.
1901 census at 1, The Hollies, Tilford Road, Farnham
1911 census at Victoria Villa, Hillbourne, Broadstone, Dorset
1913 Jul/Sep. Hugh J C Gibsone marries Elizabeth Jane Banfield. Hugh John Craig Gibsone b1864, an army officer who died in 1938 leaving £38,000. HJC Gibsone's father died in 12 May 1913 (his mother had died the year before). It would appear that he was the father of the child and did not marry the boy's mother till after the death of his parents.
