"Steelshanks" Walton's name seems to be a play on "Longshanks", a nickname of King Edward I of England, because he was tall for his era. There isn't much in the description of Steelshanks to link him to Edward I other than this line: "Steelshanks Walton stood above them, tall and dour." (A Storm of Swords, p. 612)

Firestarter (by Stephen King) reference: In "A Dance with Dragons" Melisandre recalls being sold as a child and "lot six" is heard. In "Firestarter" Lot Six is the chemical given to Charlie McGee's parents who both develop physic powers, and as Charlie grows older she develops pyrokinesis. Besides that both characters can wield fire, another rough comparison is that like Melisandre (who is purchased by the red priests), Charlie is pursued and eventually captured by the Shop, who also plan on using her for their own ends. I seem to remember reading that George R.R. Martin had a similar idea to "Firestarter" but abandoned writing it when "Firestarter" was published and the idea seemed too similar.
