The first question is what was it that your instructor's dad pass down to him? If it was strictly unarmed combat, was it hanpil, kwon bup, taekkyon or was it karate that the father may have learned?
If for no other reason than to give me insight into early KMA's, it would be interesting to know the answer to that question, but as you stated previously, it was likely done without a name.
