A Dance with Dragons
Along with the rest of House Ryswell, Roger attends the wedding of Ramsay to "Arya Stark" (actually Jeyne Poole) in Winterfell. When one of his men-at-arms is found dead at Winterfell's inner wall, Roger calls him a drunk and is skeptical that Theon Greyjoy is responsible for murders within the castle. Roger and his sister Barbrey calm six White Harbor knights who are offended by Ser Hosteen Frey. 
- The appendices of A Feast for Crows and A Dance with Dragons list Roger, Rickard, and Roose as Rodrik's quarrelsome cousins, but the text of A Dance with Dragons specifies them as his sons in 20. Reek II and 32. Reek III.
