- Stannis Baratheon: "Some highborn fools call you Onion Knight and think they insult you. So you take the onion for your sigil, sew it on your coat, fly the onion flag."
- Davos Seaworth: "My son wishes me to change it. Three mermen with tridents, something like that."

House Seaworth is a vassal house that holds fealty to House Baratheon of Dragonstone and later House Stark of Winterfell. Their lands are located on Cape Wrath in the Stormlands. Their home is a small but cozy keep near the sea.
House Seaworth is ruled by the landed knight Ser Davos Seaworth, the so-called "Onion Knight", a reformed smuggler in the service of Lord Stannis Baratheon at Dragonstone. His wife Marya and their youngest sons are usually found at their keep.
House Seaworth came into existence after Robert's Rebellion. Davos Seaworth, a smuggler infamous on the Narrow Sea for being able to smuggle anything anywhere, transported a cargo hold full of onions into the besieged castle of Storm's End, keeping the garrison alive until the war was over. Stannis Baratheon rewarded Davos by knighting him and giving him lands, though he also insisted on taking the tips of the fingers on Davos' right hand in compensation for his smuggling. Davos judged this fair, since it bought him and his family a more secure future, one he could never have imagined, much less earned for them on his own.
After Stannis is defeated and killed at the Battle of Winterfell, Davos helps Melisandre bring Jon Snow back to life. When Jon comes back to life, Davos becomes his right hand man and helps him and his family reclaim Winterfell, he declares House Seaworth's support for House Stark and Jon as the newly coronated King in the North.
- Ser Davos Seaworth, called the "Onion Knight", a former smuggler, landed knight, and advisor to King Stannis Baratheon. Current advisor to King Jon Snow.

In the books
In the A Song of Ice and Fire novels, Davos Seaworth has seven sons: Dale, Allard, Matthos, Marc, Devan, Stannis, and Steffon. The oldest five serve in Stannis' army, though the younger two are children too young to serve. Dale, Allard, Matthos, and Marc are all killed in the Battle of the Blackwater. In the TV series, these four sons have been functionally condensed into Matthos. Until now only Matthos appeared and was mentioned after his death, suggesting that he was Davos' only son.
