Researching Mary Hayley

Hayley was born in 1728 in London to the prosperous distiller Israel Wilkes junior and was a sister to the politician John Wilkes. Kind-hearted but opinionated, she lived an unconventional life and was known for her astute observation and discussion, based upon her wide reading. Refusing to bow to custom, she attended trials at the Old Bailey and travelled throughout Britain to satisfy her wide-ranging curiosity. Marrying a widower, Samuel Storke junior, in 1752, she became a widow within the year with a young step-son. As her husband's sole heir, she inherited his business and soon after his death married his chief clerk, George Hayley. He turned out to be a shrewd businessman, increasing her inherited wealth tenfold during his lifetime. Their business established extensive trade relationships with the American colonies, supplying the tea which gained infamy in the Boston Tea Party.

After her second husband's death and the end of the American Revolution, American merchants owed Hayley a large debt and she became one of the few Britons who successfully recouped their losses after the war. In 1784, she purchased a frigate used by both the Continental Navy and the Royal Navy and had it refurbished as a whaling and sealing vessel. She rechristened the frigate the United States and moved to Boston, where she lived for eight years. Unusually for women at the time, she became a benefactor, donating money and goods to charitable endeavours, and ran a whaling business. Her first venture, a voyage to the Falkland Islands, resulted in a shipment of whale oil, which was seized by the British government in 1785. She successfully recouped her losses from the Crown, as it was unable to prove that she owed duty, as British merchants were exempt if one-third of their crew was also British.

In 1786, Hayley married a Scottish merchant in Boston, Patrick Jeffrey. In 1792, she left him and returned to England with the stipulation that he never again appear in her presence. After a brief stay in London, she lived out her days in Bath.
