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 rthat 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 the page A Canadian Politician's Family.
