The Grey family, Earls of Stamford, were related to the Lumsden family by the marriage in 1834 of Mary Grey (d 1885), daughter of Rev Harry Grey (1783-1860), to James Grant Lumsden, son of Lieutenant Colonel James Lumsden. Mary Grey was the sister of Rev William Grey (1819-1872), the father of the 9th Earl of Stamford.
The Lumsdens were descended from the ancient Lumsden family of Cushnie in Aberdeenshire, whose pedigree appears in Burke's Landed gentry (London: Harrison & Sons, 1898), vol. 1, p. 948. Several members of the Lumsden family served with the East India Company in India. John Lumsden, son of John Lumsden of Cushnie, was a director of the Company. His brother David Lumsden (1765-1823) rose to the rank of Lieutenant Colonel in the Company's Bengal Army, and another brother, Matthew (1777-1835), had charge of the E.I.C.'s press in Calcutta. A fourth brother, James (d 1822), was Lieutenant Colonel of the 55th Regiment of Foot in the British Army. His sons, David (1812-1842) and John Richard (1808-1841), held the ranks of Lieutenant and Captain respectively in the Bengal Army. Their brother James Grant Lumsden (1807-1863) served the E.I.C. for over thirty years, holding various administrative and judicial positions in the Bombay presidency.
