Wylos Berrow is the lord of Holthall and the head of House Berrow.
Wylos was the first born son of the previous lord of Holthall, Temmon Berrow, and the older brother of Henron and Bessa.
Wylos became the new lord of Holthall at a young age after his fathers death (some say, killed by Lyrion Bolton and his men). He had three children, Andon, Rickon and Amyla.
He soon married his daughter Amyla to Erik Dragen, the youngest son of Lord Garth Dragen.
