According to a review in "The Journal of American History" of "Jews, Slaves, and the Slave Trade: Setting the Record Straight" (Faber) and "Jews and the American Slave Trade" (Friedman), "Eli Faber takes a quantitative approach to Jews, Slaves, and the Slave Trade in Britain's Atlantic empire, starting with the arrival of Sephardic Jews in the London resettlement of the 1650s, calculating their participation in the trading companies of the late seventeenth century, and then using a solid range of standard quantitative sources (Naval Office shipping lists, censuses, tax records, and so on) to assess the prominence in slaving and slave owning of merchants and planters identifiable as Jewish in Barbados, Jamaica, New York, Newport, Philadelphia, Charleston, and all other smaller English colonial ports." Historian Ralph Austen, however, acknowledges "Sephardi Jews in the New World had been heavily involved in the African slave trade."
