Harrold's exact relationship to Lord Roland Westerling and his daughter, Johanna, is unknown. Roland was head of their House by the Dance of the Dragons, and Johanna had married Jason Lannister to become Lady of Casterly Rock.
House of the Dragon
While Harrold Westerling's only mention in the book series is a record of his death, he is given a much more expansive role in the HBO series House of the Dragon, where his actor is part of the starring cast in Season 1. He is said to have served in the Kingsguard since the time of Jaehaerys I Targaryen, and to be a paragon of chivalry and honor.
