Elizabeth age 60 be the Nancy Elizabeth Longnecker Potterf? She may have been going by her middle name since there was already a Nancy in the home age 10? 2nd husband may have died too and she went back to her first married name since she was living with them?
History book lists her as Nancy Jane Longnecker wife of Gaspar Potterf. Gaspar died in 1836. Could this Elizabeth be Elizabethwidow of Andrew Longnecker?
