To further confuse things, there was a Joseph Hayden working in Galesburg, Knox County, Illinois, 1884-1888. I have seen two signed rifles by him, both stamped J. HAYDEN GALESBURG ILL on both barrel and lock. One was a heavy, beautifully made, target rifle with a pistol-grip stock. It was silver mounted, checkered, and had once had either a telescopic sight or a tube sight. To add to the mystery, the "J HAYDEN GALESBURG ILL" stamp was found among the tools of D. S. Hayden, who worked in nearby Monmouth, Warren County, Illinois, from 1858 on into the 1890's. So was a brand new, but bursted rifle, which was stamped " J. HAYDEN GALESBURG ILL". D. S. Hayden (David), was born in Woodsfield, Belmont County, Ohio, on August 13, 1830. He learned the gunsmih's trade from his elder brother, Joseph Hayden, in Oxford, Ohio. David S. Hayden did not have a son named Joseph.
As fine an Ohio-made rifle as I have ever seen, was made by "J. HAYDEN OXFORD OHIO". It had been in northern Illinois for many years, but may have changed hands recently, I'm not sure. It is a percussion target rifle, cased with all accessories, and covered with large and elaborate silver inlays. It is stocked in profuse burl walnut, and all accessories are also stamped with the "J HAYDEN OXFORD OHIO" stamp.
