I have always assumed that in order to bury someone a death cert had to be produced. I have two burials that I can not find a death cert for. Eliza Pickering buried 1 Jan 1922 Evergreen Cemetery, Blenheim and Vera Sinclair buried buried 3 Nov 1938 also in Evergreen Cemetery. I have looked at both Ancestry and familysearch to no avail. I would assume that if the Archives had a record they would have shown up on either Ancestry or familysearch.
