If you are TRULY interested in learning about the slaves who once lived in the State of Louisiana, FORGET ABOUT AFRICAN SLAVE SHIPS. ALMOST ALL LOUISIANA SLAVES CAME FROM THE GOOD OLD U.S. OF A. THE NEW ORLEANS CUSTOM HOUSE RECORDS OF SLAVES DISEMBARKED FROM VESSELS COMING FROM U.S. PORTS MEASURES FIFTEEN LINEAR FEET! "Congress created the Custom Service on July 31, 1789 and made it a part of the Department of Treasury (September 1789). The service assisted other agencies in the enforcement of the slave trading laws that were passed between 1794 to 1820. In particular, the 1807 law prohibited the transportation of slaves after 1808, and section 9 required that all vessels of 40 tons or more carrying slaves in the coastwise trade file duplicate manifests (ports of origin and destination) showing name, age and description of each slave, the name and residence of exporter and consignee, and pledge that the slave had not been imported after 1807. Manifest records exist for four ports.
