Silas Deane was born on January 4, 1738, in Groton, Connecticut, the son of Silas Deane, a blacksmith, and Hannah Barker Deane. He grew up in a working New England household rather than among inherited aristocracy. His father’s trade required skill and connected the family to farmers, sailors, and merchants who depended upon ironwork. The younger Silas showed academic promise and was prepared for further education. He attended Yale College, graduating in 1758. Yale’s curriculum emphasized classics, logic, rhetoric, theology, mathematics, and moral philosophy. To support himself and prepare for a profession, Deane taught school and studied law. He was admitted to the bar, but commerce soon offered greater opportunity. Deane moved to Wethersfield, Connecticut, where he served as tutor to the children of the wealthy merchant and politician Joseph Webb. He married Webb’s widow, Mehitable Nott Webb, in 1763, gaining both family responsibilities and access to a prosperous commercial network. After her death, he married Elizabeth Saltonstall Evards, granddaughter of a former Connecticut governor. Through marriage and enterprise, Deane became a merchant involved in shipping and trade. He developed the skills that later made him useful abroad: negotiation, credit, correspondence, secrecy, and the coordination of goods across long distances. He also entered local politics and represented Wethersfield in the Connecticut assembly. Before serving as an American commissioner in France, Deane had risen through education, law, marriage, and commerce. His early life encouraged restless ambition. He moved from a blacksmith’s household into Yale’s learned world and then into mercantile society, relying on personal adaptability rather than a great inherited estate. These achievements also exposed him to financial risk and dependence on complicated accounts. The same willingness to blend public service with private commercial arrangements that advanced his early career later contributed to controversy over his Revolutionary diplomacy.
