According to the LDS site the 1880 Census in Du Bois, Clearfield, PA lists:
Christian Fausey Age 70 (Self) Hannah Fausey Age 62 (Wife) Lewis Fausey Age 31 (Son) Cyrus Fausey Age 23 (Son) Jane Fausey Age 32 (Daughter-in-Law)
This shows Hannah to be alive after 1850.
I will have to go digging in my files at home, but, I think this is the family whose page I had to scan from the original 1860 (or 1850) census book at the National Archives because the microfilm was unreadable. Hannah was also listed as Christian's wife then.
