Daryl,
Actually that is in the 1910 Census records. Though the image is a bit too small. Here is a larger image. I outlined Robert Edwards in red. The last 3 columns in this enlargement give his state of birth as New York, his father's place of birth "On Ocean Welsh Parents" and his mother's place of birth as Connecticut. So it matches our man exactly.
In 1861 Robert Edwards was 15 years old. So who was the master barrel maker running the shop? Ithaca was the site of an armory. We know that the armories of the day did not merely store weapons, but also made them. That was part of the furor over the Harper's Ferry raid.
I will dig a little more and see if I can find any of the other employees working there during the 1855-1865 time frame.
