Edward Arn
Hello,
I have a book the Longriffles of Pennsylvania. By Russell Harriger. About the gun makers in Jefferson, Clarion and Elk counties. It is in out of print but can be found by searching the internet if you want a copy.
This book has a page that mentions Edward Arn, as a gunsmith apprentice to Alexander C. McGirr. I wish that it conatined more information but my The McGirr family can be of help.
I can email the page to anyone who would like them.
My second cousin twice removed wrote the book.
