Willing, Morris & Co funded its own slave-trading voyage. The ship did not carry enough to be profitable and, during a second trip, was captured by French privateers. The firm handled two slave auctions for other importers, offering a total of 23 slaves. In 1762, the firm advertised an agency sale in Wilmington, Delaware for over 100 Gold Coast slaves. The ship had docked in Wilmington to avoid the tariff. In 1765, on their last reported agency deal related to slavery (out of a total of eight), the firm advertised 17 slaves who were brought in from Africa on the ship "Marquis de Granby". The slaves were not sold in Philadelphia, as the owner took the ship and all the slaves to Jamaica.
