The second Jew known to have lived in North America was Solomon Franco, a Sephardic Jew from Holland who is believed to have settled in the city of Boston in the Massachusetts Bay Colony in 1649. Franco was a scholar and agent for Immanuel Perada, a Dutch merchant. He delivered supplies to Edward Gibbons, a major general in the Massachusetts militia. After a dispute over who should pay Franco (Gibbons or Perada) the Massachusetts General Court ruled on May 6, 1649, that Franco was to be expelled from the colony, and granted him "six shillings per week out of the Treasury for ten weeks, for sustenance, till he can get his passage to Holland."
