The SS Silesia was a late 19th-century Hamburg America Line passenger and cargo ship that ran between the European ports of Hamburg, Germany and Le Havre, France to Castle Garden and later Ellis Island, New York transporting European immigrants, primarily Russian, Prussian, Hungarian, German, Austrian, Italian, and Danish individuals and families. Most passengers on this route were manual laborers, including stonecutters, locksmiths, farmers, millers, upholsterers, confectioners, and tailors, though physicians and other professionals also bought passage on her.
