William Mitchell (1742–1823)

[1] He was the eldest son of John Mitchell of Doune, Perthshire and his wife Margaret Ferguson.

[3] While the position of Receiver General of Jamaica was held in name at the time by Viscount Sackville, the post was leased.

[1] He filled his brother's seat in the Jamaican assembly in 1798; and resigned as a Westminster MP in 1799, his place there being taken in a by-election by Richard Hankey.

He renewed the lease in 1808 with Lord George Sackville-Germain, younger brother of the previous holder, to whom the title had passed.

He left his Jamaican and Scottish property to John Mitchell, one of the five sons of his brother David, a London merchant in business with Robert Milligan.
