Guy is correct. According to the info I have been able to find to date, there are 4 Joel Atkinson in three generations of this family. I haven't been able to pin it down, but I think the rifle was made by Joel Atkinson (born 1740 in VA) that moved to Jamestown, TN from Va. Originally, I thought the Joel Atkinson that was born in Jamestown, TN made the rifle, but he couldn't have been the maker because he was born in 1840 time frame, and the date on the barrel looks like Aug 24, 1807. The only number that is a bit hard to read on the date is the 8. It came into my family the first time in 1905, so I know it is not a 9 and it clearly is not a 7. I don't think the current lock was originally flint, and the wood behind the hammer has been replaced sometime in the past, so, I can not say the mortis was originally cut for a flintlock and updated to a cap later on. The barrel could have come from an older rifle that was a flint, I haven't disassembled the rifle to see if it has any info on the underside of the barrel that would be of help, and I haven't been able to find any info on the person that Joel made the rifle for originally to date. However, the search goes on.
