True, but having read your Sussex posting you still seem not to have found her. Have you considered this option from IGI:
Nancy Tuppeny
Christening: 24 JUN 1774 Hawkhurst, Kent, England
Parents:
Father: Thos Tuppeny
Mother: Ann Tuppeny
Hawkhurst and Ticehurst are very close, on either side of the Kent/Suusex border.
