Just who was Elizabeth French Gill (1794-1854)? This wealthy, self-sufficient woman is barely acknowledged in historical reference works about Haddonfield, New Jersey, but she was an important woman in her own right and inspired and motivated her future husband, John Gill, to build as a celebration of their marriage one of the most elegant mansions in Haddonfield. Author Harriet Gotchel Monshaw explores the life of Gill from her childhood in Moorestown to her business dealings as an independent woman, her unexpected marriage at the age of 47, and her life in Haddonfield at “Greenfield Hall” mansion.
