Sir William Forbes, 6th Baronet of Monymusk and Pitsligo, usually known as William Forbes of Pitsligo (1739–1806), was a Scottish banker. He was known also as an improving landlord, philanthropist, and writer. Life and career He was born in Edinburgh on 5 April 1739. His father Willam Forbes, heir to a Nova Scotia baronetcy, was an advocate; the family estate at Monymusk in Aberdeenshire had been sold by his grandfather. Forbes's maternal grandmother was a sister of Alexander Forbes, 4th Lord Forbes of Pitsligo, whose activities in 1745 led to the forfeiture of his estate, also in Aberdeenshire. His mother, Christian Forbes, was a member of a collateral branch of the Monymusk family, and was left a widow when William, the elder of two surviving boys from a family of five, was only four years old. She settled in Aberdeen in 1745 for the education of her children, who were brought up as Scottish episcopalians.

A new partnership, including Forbes, was proposed and established in 1763. After seven years (in 1770) he married Elizabeth Hay, eldest daughter of Sir James Hay of Smithfield, Bt.
