The rule against perpetuities does not affect remoteness in the cesser of limitations1; it is the vesting of the interest that is considered, not its duration. Accordingly, an interest may be given to an unborn person for life2, or until marriage3, or until any other event4, provided it must vest, if at all, within the proper period; or to a succession of unborn persons whose interests will vest within the proper period5; or to a number of persons for life who may be unborn at the testator's death6. In each of these cases the limitation is valid without reference
