The Colvin family, for the purposes of this article, is that group of people descended from James Colquhoun Colvin (1768–1847), the son of Alexander Colvin (1718–1791) and Elizabeth 'Bettie' née Kennedy (1714–1795). James was a merchant trading between London and Calcutta during the East India Company. This Anglo-Indian family was intimately involved with the British Raj, first as traders and then as administrators and soldiers. Their descendants continued in service to the British Empire and later in some of its constituent countries, e.g. one was an Australian admiral.
In 1802 James married Maria Jackson (1778–1834) at Fort William, India. Among their children were:
- Elizabeth Jackson Colvin (1803–1856) who married her cousin Alexander Colvin (1787–1864)
- Anna Maria Colvin (1804–1867) who married Robert David Colquhoun (1786–1838)
- Bazett David Colvin JP (1805–1871) see below

- Binny James Colvin (1809–1895) who married Helen Catherine née Best (1818–1910) daughter of John Rycroft Best of Barbados
- Henrietta Hall Colvin (1812–1841) who married Rev. Ellis Walford (1803–1881)
- James Edward Colvin (1814–1814)

- Margaret Matilda Colvin (1817–1894) who married Walker Pitcairn (1808–1857)
Maria's eldest sister had married a Thomas Binny, who had traded at Madras and retired to St Andrews, Scotland. It was in their household that Bazett, John, and Binny Colvin passed their childhood.
