In the will of her father Nicholas, Abigail is identified as the wife of Richard Fenner, Esq.
Abigail is mentioned as Abigail Fenner, dec'd. in the will of her sister Lydia (Sheldon) Arnold, dated 3 Aug 1774. Abigail's four sons are also mentioned in the will. Abigail is also mentioned in the will of her husband, Richard, dated 8 Sept 1772, but she is not mentioned as deceased. This is likely because he had a second wife of the same name.
