William Sandford (1637–1691) was a colonist, planter, government official and militiaman. Born in an English enclave in The Free and Hanseatic City of Hamburg, he also lived in Surinam, Barbados and East Jersey. In partnership with his uncle, Nathaniel Kingsland of Barbados, he obtained the initial land grant for New Barbadoes, New Jersey and he and his family were the first European settlers there. He held various civil offices and was involved in several militia engagements.
