Hannah Callowhill Penn (1671-1726) – Callowhill, of Bristol, England, became the second wife of William Penn, founder of Philadelphia and Pennsylvania, in 1696. Three years later, at age 28, she accompanied her husband on his second and final trip to the Colonies. In 1712, after the Penns returned to England, William suffered a series of strokes, and Callowhill Penn took over managing the family’s proprietorship in Pennsylvania, overseeing two changes of deputy governors and advising and instructing on their governance; negotiating disputes over the Pennsylvania-Maryland border, and resolving disputes with the English government over laws passed in Pennsylvania. She continued her work for 14 years, until her death. In 1984, Callowhill Penn became the first woman Honorary Citizen of the United States. March 12 is Hannah Callowhill Penn Day in Pennsylvania.
