Lord Bracken (father of Otho)
From A Wiki of Ice and Fire
|Lord of the Stone Hedge
|In 211 AC or 212 AC, the Trident (unconfirmed)
|The Sworn Sword (mentioned)
It is unclear if he died by 212 AC or not. The conspirators of the Second Blackfyre Rebellion hoped for Otho to join the forces of House Bracken to their own, which may imply Otho had succeeded his father.
