was an English marine painter who lived between 1681 and 1749.
Peter Monamy was baptised at the church of St Botolph's-without-Aldgate, London, England, on 12 January 1681 (new style). He was the last known surviving child of Peter, or Pierre, Monamy, born 1650 in Guernsey, and his English wife, Dorothy Gilbert; and the grandson of Andre Monamy, 1612-1680, who had been a strongly committed Commonwealth Parliamentarian in Guernsey during the 1650s. Dorothy Gilbert was the daughter of James Gilbert, who was Master of the Worshipful Company of Gunmakers in 1670 and 1672. The Monamy family had been prominent merchants and residents of Guernsey since at least the 1560s, and in the Channel Islands since the 1530s. The painter's father, Pierre, had a brother named Andre, or Andrew, who was active in London as a merchant trader in salt and wool, during the late 17th and early 18th centuries. In December, 1696, Andrew Monamy, together with his cousin, Daniel Le Febvre, is described as "guardian" of the children of Peter (i.e. Pierre) Monamy, deceased. The elder Peter Monamy appears to have died in about 1685.
On 3 September 1696, Peter Monamy, aged 15, was bound as an apprentice for seven years by indenture to William Clark, a former (1687) Master of the Worshipful Company of Painter-Stainers, one of London's ancient guilds of craftsmen. Clark is recorded in several capacities in the London of the late 17th century, as a constable and juryman, with premises in Thames Street, and on London Bridge, and practised as what would today be called an interior decorator, with a thriving business. House decoration comprised a wide range of activities, including the provision of paintings as overdoors, and on panelling, house murals on canvas as well as decorative sign-boards for trade establishments. William Clark died before January, 1704, when his will was proved.
