Peck was born in Lenox, Massachusetts; his parents were Lucretia Pattison and Elisha Peck, whose ancestors had landed in America from Essex, England, in about 1635. Peck left Lenox at an early age and moved to Berlin, Connecticut, becoming involved in business with his uncle, Shubael Pattison, a tinsmith and trader. He also married Pattison's daughter, Chloe, in about 1814.
