I was thinking about this today while reading and replying on some other forums. In most of the traditional arts, lineage is a big deal. Not only does an instructors lineage help you know if they are "legit" in a sense, but it also connects us to history much like a family tree. In terms of being legit, if someone can't at least give you a bit of their lineage, then they might just be making up their rank. But in terms of history, lineage connects us to the past. I've been able to trace my TKD and HKD lineage back to my sabounim's instructor, but that's about where it ends for me (at least for those arts - my submission grappling goes a little farther but my kickboxing/boxing ends with the people who taught me). *EDIT* I "think" I have been able to trace my lineage in the Korean arts a little farther back but I'm not 100% sure. I could be missing a step possibly. How far back have you been able to trace yours? Just curious how interested folks are in their history and connection to the art.
