She was one of the aristocratic female signatories to Thomas Coram's petition to establish the Foundling Hospital, which was presented to King George II in 1735. She signed the petition on 25 April 1729, and Gillian Wagner suggests that the Bolton family members may have signed as a result of their 'personal experience of illegitimacy in the[ir] family'. Wagner also suggests that the Dowager Duchess signed with the encouragement of her step-daughter-in-law Anne, who had signed Coram's petition three days earlier, on 22 April 1729.Profile , foundlingmuseum.org.uk.
