"A cemetery may be considered as abandoned when all or practically all of the bodies have been Removed therefrom and no bodies have been buried therein for a great many years, and the cemetery has been so long neglected as entirely to lose its identity as such, and is no longer known, recognized and respected by the public as a cemetery. 1953 OAG 2978."
