John, Jr. served in the French and Indian War (1754-1763) and the Revolutionary War (1775-1783). He was a tavernkeeper in Deerfield, Massachusetts. In 1774 and 1775, entries in John Russell's account book show that Hinsdale paid Caleb Sharp's (Sharp Caleb's) debt. Sharp was of mixed African and Indigenous blood and as early as 1767, he built the first grist mill in Conway, Massachusetts.
