Initially enslaved by the Reverend John Williams, one of Deerfield’s first ministers, Mesheck was listed in Williams’s 1729 probate inventory as “the Molatto boy Meseck” and assigned a value of 80 pounds. Initially left to Williams’s daughter, Sarah, who died in 1737, Mesheck was living by 1747 in the household of Williams’s daughter, Abigail and her husband, Colonel Ebenezer Hinsdale. He was both baptized and admitted to the church. Mescheck actively assisted Hinsdale by running his stores in Hinsdale, New Hampshire. Mescheck likely lived alongside Caesar in the Hinsdale household.
