Sarah Franklin Bache (1743-1808), a Revolutionary War patriot and daughter of Benjamin Franklin, led an active public life according to the standards of womanhood in the late eighteenth century. As the daughter of Benjamin Franklin she had an unusual access, for a woman, to the political life in revolutionary Philadelphia. Although her primary role was of caretaker of her family and home, Bache played an active role in the Revolution through her relief work and as her father's political hostess. The Sarah Franklin Bache papers consist of incoming and outgoing correspondence ranging from 1768 to 1807 mostly of a personal nature to and from friends and relatives. The correspondence of her relatives includes her nephew William Temple Franklin, her brother William Franklin and her children.
