When given a facial consideration, the first sentence of the will provision in question amounts to a contingent remainder limited as to an event. Napier v. Napier, 211 Ga. 145 ( 84 S.E.2d 56) (1954); Bailey v. Johnson, 245 Ga. 823 ( 268 S.E.2d 147) (1980). The defeat of this conclusion requires a strong showing of contrary testamentary intent by consideration of the entire will. While the argument of the executors is arresting, it falls short of being compelling.
