Stephen Moore, 3rd Earl Mount Cashell

Stephen Moore, 3rd Earl Mount Cashell (20 May 1792 – 10 October 1883), styled Lord Kilworth until 1822, was an Anglo-Irish aristocrat and politician who spent much of his life in what is now Canada.

Using the services of an agent Lord Mount Cashell purchased 1,000 acres (4.0 km2) from the estate of the late Captain John Matthews, an Upper Canadian politician and former officer in the Royal Artillery who had come to British North America in the retinue of Governor-General Charles Lennox, 4th Duke of Richmond.

Settling on the former Matthews' estate Mount Cashell built – by Upper Canadian standards – a large home for his family and servants.

Various members of the family travelled between Britain and the lands in British North America and Mount Cashell's daughter-in-law, Jane Dance, wife of the Hon.
