's sketch of Ham House, June 1835 A portrait of Louisa by Sir
Joshua Reynolds was engraved by
Valentine Green, and another by
Hoppner, as a peasant, has also been engraved. Hoppner's portrait was sold at Messrs. Robinson and Fisher's rooms for 14,050
guineas on 27 June 1901. This portrait originally belonged to Louisa's daughter, Lady Laura Tollemache, from whom it passed to Louisa's granddaughter,
Maria, Marchioness of Ailesbury, and finally came into the possession of the latter's daughter-in-law, the
Lady Charles Bruce, by whose executors it was sold.
Thomas Lawrence's portrait of Lady Louisa was exhibited at the
Royal Academy in 1794. Louisa was a notable patron of
John Constable, entertaining him at Helmingham, Ham House and London residences at
Pall Mall and in
Piccadilly. Constable's letters make several references to Lady Dysart and he was evidently at ease with the family. Louisa employed his brother, Golding Constable, as
gamekeeper at Helmingham. Others to derive works from Hoppner, Lawrence and Reynolds portraits of Louisa include
Henry Bone,
Charles Knight and
Richard Smythe. ==Title==
