- Cornelius Cayley (1762-1836), another Russia merchant, who spent most of his life helping to look after the England end of the business, and retired to Sowerby in Yorkshire. In 1784 he married Sarah Ward (1763-1846). They had three children:
- Cornelius John Cayley (1786-1862), who spent most of his life at Sowerby and never married
- Elizabeth Sarah Cayley (1788-1871), who married James Favell of Normanton, Yorkshire – one of their grandchildren was Arthur Cayley Headlam (1862-1947), who was appointed Bishop of Gloucester in 1923, and who was keenly interested in ecumenical affairs
- Sarah Cayley (d. 1857)
- George Cayley (1763-1831), who practised as a doctor in Russia, including two years as a medical officer with the Russian army before setting up a practice in Moscow. In or before 1798 he settled as a doctor in Durham. He was a close friend of a number of Russians, including the anarchist and revolutionary Mikhail Bakunin. He was buried in Durham Cathedral.
- Sarah Cayley (b. 1764), who in 1785 married Edward Moberley, a member of another family of English merchants in Russia
- Ann Cayley (1765-1766)
- William Cayley (1766-1803), yet another Russia merchant, who succeeded his father as British consul in St Petersburg, where he died a few years later. In 1792 he married Elizabeth Cavanaugh (1764-1852) in St Petersburg: after his death she settled in Southwell, Nottinghamshire. They had two children:
- William Cayley (1798-1802)
- Maria Elizabeth Cayley (c. 1804-1876), who was born after her father’s death and moved with her mother to Southwell, where she lived until her death.
- Henry Cayley (1768-1850), who was one of the Cayley merchants in St Petersburg, where he married Mary Antonia Doughty (c. 1799-1875) in 1814. Probably in the 1830’s they moved to London, where he continued his business interests
John Cayley and Harriette Raikes had ten children:
- Lucy Cayley (1802-1803), who was born and died in St Petersburg
- Another Lucy Cayley (b. 1803 in St Petersburg, d. 1870), who married the Rev Charles Edward Hutchinson in London in 1829: he was a Sussex clergyman and a canon of Chichester Cathedral
- Edward Cayley (1805-1871), who never married. He was born in St Petersburg, and stayed on for some years in Russia after most of the family returned to England, though he settled in England before his death.
- William Cayley (1807-1890), who was born in St Petersburg, and qualified as a barrister in London. He moved to Toronto in about 1836, practising law there. He became a prominent Canadian politician, despite losing large sums of money when a firm he was involved in went bust. There were rumours that he was insolvent, but he came through and acquired other valuable business interests. A bank of which he was a Director got into difficulties in about 1860, and the following year the shareholders voted not to reappoint him. The bank collapsed five years later. As a politician he was a Conservative, and served more than one term as Inspector-General for Upper Canada, a post with financial responsibility. He was an advocate of tariffs to protect Canadian produce. He failed to plan sufficiently for the potential difficulties being caused by growth in government spending, and lost his seat in the Canadian Assembly when a recession brought a crisis in 1857. He resumed his legal practice, and also became Chairman of the Dominion Telegraph Company. From 1870 to 1877 he was auditor of Ontario. He died in Toronto. In 1836 he married Emma Robinson Boulton (1818-1890), daughter of a leading Conservative politician. For their descendants, see A Canadian Politician’s Family.
