The author of this post, Jerry Quinn, is a friend and fellow writer. He’s helped me out with questions of kings and castles in the past. He has a thorough and expert knowledge of feudal culture and is generous with sharing that knowledge to those of us less gifted in that area!
I’m sharing this link as much for my own benefit (so I can easily find it next time!) as for everyone else. It’s a good, entertaining read as well as an informative one.
