Got facts False, actually. tommen was the son of cersei and Jaime (spoilers!) so when stannis Baratheon died on the battlefield, slain by brienne of tarth, house Baratheon then became extinct because he'd killed his daughter, and his brothers were dead
Shireen Baratheon is the daughter and only child of Lord Stannis Baratheon and Lady Selyse Florent. Shireen is regarded as a sweet child, but she is not considered very pretty. She has blue eyes, but inherited both her father's square, jutting jaw and her mother's large ears. The greyscale caused half of her left cheek and most of her neck to be covered in gray and black dead skin. She is nine years old.
