It depends on how they hold title. Joint tenancy, no their children would have no interest in the property, tenants in common, possibly. You should discuss this with an attorney so that the relevant documents can be reviewed.
Joint tenancy property passes to the surviving joint tenants not to the descendants.
On the death of the last survivor it passes to the survivor's estate.
