There are many theories  about  King Jon Stark III's mother. Some outrageous claims propose that Jon Stark was the fruit of a sordid affair between Queen Rhaella Targaryen and Eddard Stark, but there's little proof. The  Breaker  himself claims  not to  know who his mother was, as Lord Eddard Stark passed away before he could tell him. Another popular theory is that his mother is Ashara Dayne. While this theory looks plausible since Eddard Stark and Ashara Dayne danced during the Tourney of Harrenhal, it falls short as the Dayne beauty had given birth to a stillborn girl towards the end of the rebellion.
