Wish I had more time to get into this as a black louisianan but I will say with 100% clarity the bulk of new orleans black population came straight from the senegambia region in the 1700s. The 1809 immigration of Haitians doubled the new orleans population to 20,000 but one third of those who came were 'white' Haitians. That's about the same amount OR less than the current population of blacks inhabiting the city during that period. There were about 13 to 14 ships throughout the 1700s that arrived from the senegambia region carrying 500 to 600 slaves each, that's anywhere from 6,500 to 8400 blacks in the city before the big 1809 immigration. Now again, as far as the 'transfroming' aspect of the native slave populace you have to know these people were highly skilled farmers and craftsmen without those slaves from the senegambia region we might not be talking about a city of new orleans or haitian immigration right now. The French were inexperienced with the landscape of new orleans, slaves from the senegambia thrived on the bank and opened the door for the area to boom with new possibilities. The slaves from the senegambia brought the rice cultivation, introduced beans, okra, vodou and the type of foundational building that made it feasible to live by the river.
Also, new orleans is BIG on gris gris in vodou, the parallels between how amulets are used today in the senegambia region and gris gris bags in new orleans basically just reinforces how influential those who arrived in the 1700s were.
