In Georgia if spouse dies without a will and property and home have only his name on deed and he has 2 grown kids and she is 2nd wife does she have any rights or does everything go to his kids?

From the Georgia Code: (1) Upon the death of an individual who is survived by a spouse but not by any child or other descendant, the spouse is the sole heir. If the decedent is also survived by any child or other descendant, the spouse shall share equally with the children, with the descendants of any deceased child taking that child's share, per stirpes; provided, however, that the spouse's portion shall not be less than a one-third share . . .
