in ensuring the guilty verdict that the judiciary required. Grove did sit as one of five judges on the final determination of the case in the Divisional Court of the Queen's Bench. Grove was a careful, painstaking and accurate judge, courageous and not afraid to assert an independent judicial opinion. However, he was fallible in patent cases, where he was prone to become overinterested in the technology in question and to be distracted by questioning the litigants as to potential improvements in their devices, even going so far as to suggest his own innovations. He retired from the bench in 1887. His portrait was painted by Helen Donald-Smith in the 1890s. Family Grove married Emma Maria Powles, daughter of John Diston Powles, in 1837, and had several children, including Major-General Sir Coleridge Grove. Groves's daughter, Imogen Emily (died 1886), married William Edward Hall in 1866. His daughter Anna married Herbert Augustus Hills (1837–1907) and was mother to Edmond Herbert Grove-Hills ("Colonel Rivers") and John Waller Hills. His health perpetually troubled, Grove died at home, 115 Harley Street in London, after a long illness. He is buried in Kensal Green Cemetery, London. Honours Grove became a Fellow of the Royal Society in 1840, and received its Royal Medal in 1847. He was Vice-President of the Royal Institution in 1844. Receiving a knighthood in 1872, he was given an honorary degree by Cambridge University in 1879 and became Privy Councillor in 1887. The lunar crater "Grove" is named in his honour.
