Currently, the Game of Thrones universe is defined by Targaryen family. House of the Dragon follows the Dance of the Dragons succession battle between Rhaenyra Targaryen and Aegon II. A Knight of the Seven Kingdoms follows Rhaenyra’s great-great-great-great-great-grandson Maekar and his sons Aerion and Aegon, and then Game of Thrones picks up with Aegon’s great-granddaughter Daenerys.
However, that’s not the only family connection between the different shows. Lyonel Baratheon, the “Laughing Storm” who parties with Dunk during the first night of the tourney, is either the great-grandfather or great-great-grandfather of Robert Baratheon (who is also a great-grandson of Egg.)
