Oliver's wife was also an artist and, like her husband, exhibited at the British Institution, the Society of British Artists and the Royal Academy. After Oliver's death she travelled further afield than when he was alive, often painting in foreign locations that he had previously visited. She remarried, in about 1856, to John Sedgewick, a solicitor of Watford, Hertfordshire, but continued to follow her profession in her first husband's name until her death at the Brewer's House, Berkhamstead, on 5 March 1885. She was elected an associate member of the New Society of Painters in Water-Colours in 1849 but was not made a full member until the year of her death.
