Although Brooke died unmarried, he did acknowledge a son to his family in 1858. Neither the identity of the son's mother nor his birth date is clear. This son was brought up as Reuben George Walker in the Brighton household of Frances Walker (1841 and 1851 census, apparently born ). By 1858 he was aware of his connection to Brooke and by 1871 he is on the census at the parish of Plumtree, Nottinghamshire as "George Brooke", age "40", birthplace "Sarawak, Borneo". He married Martha Elizabeth Mowbray on 10 July 1862, and had seven children, three of whom survived infancy; the oldest was named James. George died travelling to Australia, in the wrecking of the SS British Admiral on 23 May 1874. A memorial to this effect – giving a birthdate of 1834 – is in the churchyard at Plumtree.
