I recently came upon this portrait of Lady Mary Booth (1704-1772) and was struck by her lively and open expression.
Lady Mary was the heiress to the Dunham Massey estate. Unusually for the time, her father, the 2nd Earl of Warrington, wanted his only daughter to have full control of her property. He left it in trust for her benefit, rather than leaving it to her outright, so that when she married it wouldn’t automatically be transferred to her husband.
When she did marry in 1736, at the relatively late age of 32, it was to the much younger Harry, Lord Grey of Groby, later 4th Earl of Stamford. She was the linchpin that brought the Booth and Grey family estates (at Dunham Massey and Enville Hall, respectively), together.
Although it was probably an arranged marriage it seems to have been a succesful one. The Countess of Stamford was highly educated and intellectual, and the books with her bookplate in the Dunham library include natural history, poetry, plays and religious topics.
She also developed the New Park at Dunham, where she may have employed Lancelot ‘Capability’ Brown to create one of the newly fashionable landscape gardens.
