The first name is Fritz and the last is Patrick .. When pronounced it sounds like one word. ( Fitzpatrick) For some time I thought it was one word. I know of no initial. But have been told he sometimes inlaid a gold horn of plenty. He made both knives and guns and worked with Stephen Odell of Natchez Ms before going out on his own.
I appreciate your response and if you recall anything about the one you have seen , let me know,,,Louie
