Harriette Anne Morrell (1845-1924), née Wynter, was the daughter of Rev. Philip Wynter (1793-1871) and his second wife, Diana Ann Taylor. Wynter was President of St John's College, Oxford (1828-1871) and Vice Chancellor of the University of Oxford (1840-1844).

In February 1867, Harriette married Frederic Parker Morrell (1839-1909). Morrell was a solicitor and was elected Mayor of Oxford in 1899. The family lived at Black Hall, Oxford. They had two daughters and two sons: Margaret 'Margie' Cecil Louisa (b.1868), who married the architect Edward Prioleau Warren (1856-1937) in 1894; Frederica 'Freddy' Harriette (b.1869), who married John Douglas Peel, a solicitor, in 1905; Philip Edward (1870-1943), a Liberal MP who was educated at Eton and Balliol College, Oxford, and who married the society hostess Lady Ottoline Cavendish-Bentinck in 1902; and Hugh St John (1872-1898), of the Cheshire Regiment, who died onboard SS Lagos in 1898.

Known for her artistic ability, Harriette was said to be the inspiration for Henry James's character Adela Gereth in his novel The Spoils of Poynton.
