Lieutenant Colonel George Washington Gibson, shows the following dates of rank, campaign service, and army appointments related to his service in the British Army:[1]
Probably from the marriage of 4 June 1838 (there is some uncertainity), two children were born to George Washington Gibson and Charlotte Elizabeth, a daughter, Charlotte Elizabeth, in 1823 in Holybourne, Hampshire, and a son George Rawstorne in 1824, in the same place.
Mary Hannah Barnes was married to George Washington Gibson, in London on 15 December 1852 with her father, James, present. Her parents had only recently returned from South Africa. Mary Hannah was 29 years old, while her husband was some 28 years her senior. The marriage was childless and the thought occurs that this marriage to a much older man was one of practical convenience; without it, Mary Hannah would have been left quite alone. Both her parents were seriously ill and dead within a matter of months after her marriage. At the time of her marriage her three brothers were fighting in the 3rd Kaffir War in South Africa.
When George W. Gibson died in Kensington in 1872, the body was taken
to Portishead, Somerset County, and buried in St. Peter's churchyard next
to James and Hannah Barnes, his wife's parents. Mary Hannah was later buried
there as well. The monument inscription reads:
