|House Ryder of the Rills|
|Current Lord||Possibly extinct|
The Ryders were First Men kings after the Long Night who were eventually defeated and reduced to vassals by the Kings of Winter, House Stark of Winterfell. The Ryders are possibly extinct, as they have not been mentioned in A Song of Ice and Fire and House Ryswell now rules the Rills.
