A tree at ancestry says Gertrude Gladys (Boughton) Cosby died 17 December 1983, presumably somewhere near her 1974 residence.
The tree also says her husband Orland Clifford Cosby died 1 March 1981 and is buried in Pleasantview Memorial Gardens, Fonthill, Ontario. No source for either date
They are said to have had a son Carmon Orland Cosby (1931 - 11 December 1968), buried Mt Osborne Cemetery, Beamsville, Niagara, Ontario, Canada.
and a daughter May Kathleen (Cosby) Harris (1933 - 8 April 2010, Welland Hospital, Welland, Ontario). Her husband Albert William Harris said to have died 25 June 2003, same hospital.
also a son, marked private in the tree.
