Duchess of Portland (1783 ship)

The Duchess of Portland was a merchant ship built in 1783. She was primarily engaged in trade between Great Britain and the East Indies under license from the British East India Company (EIC). Little readily available detailed information exists regarding her specific voyages, ownership changes, or eventual fate, making a comprehensive history difficult to compile without further research in primary sources. She appears in shipping registers of the period, confirming her existence and general purpose.
