Where a marriage is annulled on the ground that a former husband
or wife was living, and it is adjudged that the subsequent marriage was
contracted in good faith and with the full belief of the parties that the
former husband or wife was dead, or when a marriage is annulled on the ground
of insanity, children begotten before the decree is made shall be specified in
the decree, and shall be entitled to succeed, in the same manner as legitimate
children, to the estate of the parent who at the time of the marriage was
