Who was known as a gambler and plantation owner in the Faubourg Marigny?

Bernard de Marigny is recognized as a notable figure in the Faubourg Marigny neighborhood. He was a gambler and plantation owner who played a significant role in the early development of the area just outside the French Quarter of New Orleans. Marigny was instrumental in promoting the region by dividing his land into lots and selling them to others, thereby attracting new residents and businesses. His lifestyle and interests in gambling were characteristic of the vibrant social scene in New Orleans during the 19th century, which was deeply influenced by leisure and entertainment.

The other individuals mentioned do not have the same affiliation with the Faubourg Marigny or the context of being known primarily for gambling and plantation ownership. Paul Morphy was a celebrated chess prodigy, Andrew Jackson was the seventh President of the United States and a military leader, and Nicholas Roosevelt, while related to the Roosevelt family, is more known for his role in the steamboat industry rather than gambling or plantation ownership in New Orleans. Thus, Bernard de Marigny stands out as the key figure associated with the characteristics described in the question.
