Sir James John Trevor Lawrence, 2nd Baronet, KCVO (30 December 1831 – 22 December 1913), known as Sir Trevor Lawrence, was an English horticulturalist, collector and politician.
Lawrence was born on 30 December 1831, the son of Sir William Lawrence and Louisa Senior, the daughter of a successful Mayfair haberdasher who had bought a country estate, Broughton House, near Aylesbury, Buckinghamshire. He was educated at Winchester College and at St Bartholomew's Hospital, where he took the diploma of MRCS in 1853. He then worked for nearly ten years for the Indian Medical Service. Having inherited his mother’s particular love for orchids, he reinforced this when he was in India. He made his first collection when living at Dharamsala in the Himalayan foothills.
On 5 July 1867, Lawrence succeeded to his father's recently created baronetcy (see Lawrence Baronets). In 1869 he married Elizabeth Matthew, daughter of John Matthew, a partner in the leading firm of marine engineers, John Penn and Son of Greenwich. She inherited Burford Lodge, near Dorking, where they created a celebrated garden. The estate then included the Burford Bridge Hotel. They had three sons and one daughter:
