Ser Willem Frey is an unseen character mentioned in second and third season. He is a member of House Frey and a knight whose wedding was celebrated with a tournament some time before the series began.
Ser Alton Lannister recalls squiring for his distant cousin Ser Jaime Lannister at the tournament. Jaime defeated Ser Balon Swann. The day was one of Alton's proudest achievements and he was disappointed when he had to leave the field to eat at the periphery of the wedding feast.
In the books
In the A Song of Ice and Fire novels, there is a character named Willem Frey but he is a young grandson of Lord Walder Frey and the second son of Ser Cleos Frey (the analogous character of Ser Alton Lannister) and Jeyne Darry. This "Willem Frey" is only ten years old, and thus was never married. He serves as a page at Ashemark. He does not make an appearance in the books so far, and is only mentioned in the appendix.
