Her library at Eshton Hall in Yorkshire exceeded 20,000 volumes, including printed books in many fields and some MSS. She enjoyed a close friendship with Heber and was admired by Dibdin. The bulk of her library was sold at Sotheby's on 30 July 1862 and realized nearly £6,000. Most of the remaining works were sold there on 31 May 1916 and made £3,700.
