He was born in London to the English-born Australian politician John Lamb, who was a commander of the Royal Navy, and Emma Trant. His mother was the daughter John Robinson of Holloway, who was the deputy chairman of Lloyds Bank.[3] His father Commander John Lamb was the chairman of the Commercial Banking Company of Sydney (now National Australia Bank), of which he and his brothers Alfred Lamb, Edward Lamb and John de Villiers Lamb were directors. His sister-in-law by John de Villiers Lamb, Henrietta Lamb (née Smith), was the sister of Thomas Smith, who was the deputy chairman of the Commercial Banking Company of Sydney, and who was the nephew of Henry Smith, who was the chairman of the Commercial Banking Company of Sydney. Thomas Smith was further a brother-in-law of Australian politician John Street, patriarch of the Street family.[4] Lamb's family migrated to Sydney in 1829, and, after his education, Lamb became a clerk in his father's mercantile firm and became a partner in 1847. At 15, he became a clerk in his father's firm and at 22 a partner in Lamb, Spry & Co.[1]
On his return from a visit to England in February 1857 he, his brother John and Charles Parbury carried on as Lamb, Parbury & Co. In January 1855, Lamb had become an original shareholder and director of the Colonial Sugar Refining Company and in 1880 chairman. By 1860, he was a director of the Commercial Banking Co. of Sydney, the Australian General Assurance Co. and the Sydney Exchange Co., and had served on the committees of the Sydney Chamber of Commerce and the Union Club. He remained active in the family firm until 1863, when he became a pastoralist with a large orchard and fruit cannery. He was an early director of the Colonial Sugar Refining Company, and he was an active member of the Anti-Transportation League. In 1889, he was appointed to the New South Wales Legislative Council, where he served until 1893. Lamb died at Rooty Hill in 1906.[1]
