Background
Historical Occupation Profiles explain what ancestors actually did for a living and how those occupations shaped the records genealogists rely on today.
Occupation Overview
Merchant sailors transported goods and passengers aboard commercial vessels operating along coastal, river, and international trade routes. In the eighteenth, nineteenth, and early twentieth centuries, merchant shipping was essential to commerce, immigration, and communication.
Merchant sailors worked on cargo ships, steamships, packet ships, and other commercial vessels carrying products between ports around the world. Their work connected local communities to national and international markets.
Unlike naval personnel, merchant sailors worked in commercial shipping rather than military service.
