Administrative History: Flahavan & Willcox was a Philadelphia firm established for the import/export trade in 1784. The firm consisted of Thomas Flahavan and Mark Willcox who formed a co-partnership in 1784.
Formerly, it was named John Flahavan & Co. but was renamed when John Flahavan was lost at sea in 1783. Credit was established with European and West Indies suppliers for the import of dry goods, hardware, coffee and rum. At the same time, the firm bought tobacco, corn, mustard seed, and animal skins and exported those products from the port of Philadelphia. Flahavan & Willcox were dependent on securing able ships and sloops for transporting merchandise and correspondence. Flahavan and Willcox gave considerable attention to collecting debts and the management of lands and other property. Apparently, the firm remained successful until 1792 or later.
