Isn't it possible that Doan may not be Marle's decendant? I mean, sure he may of been related to her, but I mean maybe with Marle out of the picture the king either A. Had another child to pass on the throne to [ Not Likely ] or B. That some relative of his assumed the throne when he passed on? Making Doan still related to Marle, just not decended from her persay.
