Great entrance post.
For the record, Robin, Sleepy Pate, and Haken are the only named charactets who'd recognize Roy Stone easily (having for one reason or another guarded or paid the mine workers frequently). Ser Laton, Ser Jarl, and Mhyrko would need a successful Challenging (9 or higher) Status or Cunning: Memory test to recognize Roy. Of course, they're more than able to let it slide and accept the story on the word of the other three.
