John Jacob Negley, 1766-1827, married Barbara Anna Winebiddle in about 1795. Published sources and Barbara Anna's grave stone in Allegheny Cemetery (Pittsburgh) say she died in 1867.
IF that is correct, who is the May E. Negley, age 90, living with George Gibson Negley at the time of the 1870 census?George is a son of John Jacob and Barbara Anna. May E. Negley is included in the census listing AFTER George, his second wife, and Henry (a son of George and his first wife); BUT she is listed before 5 children from George's second wife.
Aside from the published (print and electronic) sources and the grave stone which all agree on the 1867 death date for Barbara Anna Winebiddle Negley, where else might I look to find evidence of Barbara Anna's death date and year?
