Gill Coe Antiques & Interiors has dated this piece to the Victorian era.
Lady Sybil Eden was the daughter of Sir William Grey, a former Lieut. Governor of Bengal and Governor of Jamaica.
They had five sons, one of whom died at birth. They never divorced but eventually lived separate lives. Lady Eden died on 17 June 1945, aged seventy-eight.

Their daughter, Elfrida Marjorie Eden (1887-1943), married Guy, Lord Brooke in 1909 and became Countess of Warwick in 1924.
Lady Sybil was friend with Florence Nightgale.
On 4 March 1895 Eden brought an action against Whistler because the artist refused to hand over the portrait he had been commissioned to paint of Lady Eden, Brown and Gold: Portrait of Lady Eden y408, Whistler being dissatisfied with Eden's payment. Whistler lost but, believing that as an artist he had the right to withhold any work with which he was not entirely happy, appealed in the courts on 15 December 1897 and the decision was reversed and he was allowed to keep the picture, on the proviso that it was made irrecognisable.
Lady Eden was also painted by Philip Wilson Steer (1860-1942) in 1896, and by John Singer Sargent (1856-1925), whose portrait was exhibited at the Royal Academy in 1907.
