"Not too ancient. And that's not the only person in House Baratheon with Targaryen Blood. There was a Velaryon marriage more than two hundred years ago. And Shireen's great-grandmother was Rhaelle Targaryen, the daughter of Aegon the Unlikely" the elder sister countered after a short pause. "Robert Baratheon claimed the Iron Throne both by blood and by conquest. And it doesn't matter anymore, does it? You cannot afford any other House in the North to gain a dragon through marriage with Shireen."
