- To make a profit for the Virginia company, settlers have ventured into numerous small industries, including glass making, woodworking, resin, tar, and mineral fertilizer production. However, until colonist John Rolfe (who later married Powhatan's daughter Pocahontas) introduced tobacco cultivation around 1613, a money-making plant, none of the colonists' attempts to establish a profitable business proved successful.
