House Seaworth

House Seaworth of Cape Wrath is a noble house that holds fealty to House Baratheon of Dragonstone.

Their lands are located in the Stormlands. Their home is a small keep near the sea called Cape Wrath

House Seaworth is ruled by the landed knight Ser Davos Seaworth, the so-called "Onion Knight", a reformed smuggler formerly in the service of Lord Stannis Baratheon at Dragonstone. His wife Marya is usually found at their keep.

House Seaworth came into existence after Robert's Rebellion. Davos, 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's 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.

In the books
In the A Song of Ice and Fire novels, the full name of Davos's house is House Seaworth of Cape Wrath.

Davos has seven sons; the oldest five serve in Stannis's army, while the younger two are still children. In the TV series, the five elder sons have been functionally condensed into Matthos. Until now only Matthos appeared and was mentioned after his death, suggesting that he was Davos's only son.
