LONDON.- A painting of Harriet Rushout, one of the celebrated sisters and society beauties known as 'The Three Graces' born to John Rushout, Baron Northwick of Northwick Park (1738-1800) and his wife, Rebecca is in Bonhams Fine Miniature Portrait sale on 19th November in Knightsbridge. It is estimated to sell for £8,000-12,000.

Lot 103 shows Harriet Cockerell née Rushout (d.1851), wearing a white dress and white bandeau in her powdered hair. The Henry Bone (1755-1834) preparatory sketch for this portrait, dated 1810, is housed at the National Portrait Gallery.

Harriet married Sir Charles Cockerell, 1st Bt. on 13 February 1808 and the couple had a son, Charles Cockerell Rushout, 2nd Bt. (1809-1869) and a daughter, Harriet Anne (b.1812).

It is easy to see where Harriet got her looks from as a portrait of her mother Rebecca, also in this sale as lot 102, is estimated to sell for £7,000 to £9,000.

Lot 102 shows The Hon. Lady Rebecca Northwick née Bowles (1740-1818), wearing white dress and fichu wrapped around her neck, her hair powdered beneath a white turban.

Rebecca Bowles was the daughter of Humphrey Bowles and Hannah Hurst. On 3 June 1766 at Wanstead in Essex, she married John Rushout, MP (1738-1800), 1st Baron Northwick of Northwick Park. The couple had three daughters, Anne (d.1849), Harriet (d.1851) and Elizabeth (1774-1862), and two sons. The sisters were renowned for their beauty and charm during their lifetimes and the sisters were painted together many times.
