Genna Lannister

Genna Lannister is the only daughter of Lord Tytos Lannister of Casterly Rock. She is the younger sister of Tywin and Kevan and the elder sister of Tygett and Gerion. Her father wanted badly to be liked, a weakness Lord Walder Frey turned to account in securing her for his second son Emmon when she was seven and Emmon fourteen; they have four children. Shapely in her youth, she is heavy now and square of figure, with a broad, smooth face. She is clever, shrewd and used to being obeyed, she orders her husband about and thinks him inept, and she is savagely honest: she once told Tywin to his face that Tyrion was truly his son, and their dealings were colder for it.
