I found this link that goe's into detail about anything and everything to do with mountain men. I get bored and looked around and found info on Sam and Jake Hawken the gunsmiths. Their father C. Hawken was a gunsmith too and made "Kentucky rifles" in Hagerstown Maryland. I'm unsure if it was C. Hawken's father or grandfather N. Hachen who was also a gunsmith but died too young to have trained his son but may have trained George Shroyer. N. Hachen came to America from Bern Switzerland in 1750 along with two brothers one of which was Wolfgang Hachen (Haga) the famous Berks county gunsmith. I think gunmaker Peter Gonter was Wolfgang's son in-law. Kind of like connect the dots. I said I was bored! Hope I didn't mess up this too badly. Here is the mountain man link.
