Charles M. Hayden was born in South Thomaston, Knox County, Maine, and spent the majority of his life there. Though US Federal Census records continuously identify Hayden as a farmer, he clearly had a penchant for engineering and invention. The earliest patent located for Hayden is the 1870 patent accompanying the archive, with other patents on record including one for a "Solo Pressing Machine" (1873) and a "Jig-Saw" (1874). It unclear when or if the gun mount here was patented.

Curial's correspondence is primarily directed to his sister Rachel Curial Banton (1824-1897) and her husband William H. Banton of Maine. The Bantons were the parents of Jessie Banton Hayden (1857-1919), the wife of Charles M. Hayden.
