Just to update you both in case I have not done so before.
George John CHILD married Catherine Ann Crickmay in 1864 in Kensington London. Their son George William was born in 1866 at Kingsto upon Thames.
He was living in Yorkshire, England nearly 200 miles north of his wife and son in 1871.
I found a record of George John Childs divorce from his wife Catherine Ann when a third party named Pennington was cited. This occurred in 1873 and the Divorce register number if you wanted to get more info was 2714.
George William went on to be a Bank Official, married twice, died in 1951 in Chichester, Sussex. He has a living grandson resident in UK with whom I am in touch.
There is a mystery here because George William had two daughters and there is some connection with my two mystery women: Algorta Marjorie Blanche CHILD aka Diana who married Sir Archie HAMILTON Bart and Nahneen Helen Yvonne CHILD who married (1) Captain Claude Hayes in 1913 who died on the Somme in 1916 and (2) my Great Uncle Frederick Beaconsfield PENTLAND. The mystery is who were their fathers!
