Ramsay Snow, better known as "The Bastard of Bolton"', is Lord Roose Bolton's bastard son and only living child. He stayed behind at the Dreadfort when his father left for the south to fight in the War of the Five Kings.

In the books
Ramsay Snow is Roose Bolton's bastard son. A violent sociopath, Ramsay is pervasively engaged in acts of random cruelty. He is savage and wild, almost semi-feral. Ramsay has an ugly, fleshy appearance, is perpetually filthy, and has long matted hair. He killed Ramsay's only trueborn son, his own half brother. Ramsay has a strong penchant for the House Bolton pastime of flaying their enemies alive. Ramsay himself is known for hunting peasant girls for sport with his pack of dogs. The lucky girls are killed by Ramsay after he rapes them, and then flayed. The unlucky ones are raped by Ramsay, then flayed alive.

Ramsay becomes a more prominent character in later books in the series.
