I learned that my gr-gr-gr, etc etc grandfather, Casper Dull/Doll was one of many gunsmiths in Pennsylvania who made the guns that were used by the American Revolutionary War. Even to this day, it is possible to find gun collections that allow descendants like myself to "touch a piece of history" that our own ancestor created.
I therefore think it would be interesting to network with other descendants of other ARW descendants who also have this common tie to that war & who may be interested in discussing this piece of our history & perhaps we can also track some of the guns exhibited around the country that's maker is identified.
There is currently a book in print that relates to the Guns of the American Revolution that came out of Pennsylvania. This book lists the gunsmiths & is a great genealogical tool in that sense.
