The fee shall, at the decedent's death, vest at once in the decedent's surviving child or children, or the descendants of the decedent's child or children who may be dead. A second or subsequent childless spouse described in this subsection shall, however, receive the same share of the personal property of the decedent as is provided in subsection (b) with respect to surviving spouses generally.
and one (1) of the shares shall pass to each of the brothers and sisters of the decedent's parents or their respective issue per stirpes.
If a parent is disqualified from receiving an intestate share under this subsection, the estate of the deceased child shall be distributed as though the parent had predeceased the child.
