I am having trouble finding any death records for my great grandmother, Emily Evans Roberts and her family.

Parents: Hannah Thomas (1869-?) and John J Evans (1867-1941)
Birth: 27 Nov 1896 in Bethesda, Caernarvonshire, Wales
Death: 1959 in Granville, New York.

Siblings: Edward, Stephen (1895-?), Myfanwy (1901-?), Olwen (1904-1986), and Charlotte (1911-?).

Married Hugh Roberts (1894-?) about 1919.
Children: Florence Jones (1916-?), Evelyn Waynick(1925-P) and Elinor Retallack (1927-P).

My grandmother says Emily and serveral family members are buried in the Granville Cemetery but I have found no cemeteries by that name. Can anyone help?
