Delphine LaLaurie and her third husband, Leonard LaLaurie, took up residence in the house at 1140 Royal Street sometime in the 1830's. The pair immediately became the darlings of the gay New Orleans social scene that at the time was experiencing the birth of ragtime, the slave dances and rituals of Congo Square, the reign of the Mighty Marie Laveau, and the advent of the bittersweet Creole Balls. Madame LaLaurie hosted fantastic events in her beautiful home that were talked about months afterward. She was described as sweet and endearing in her ways, and her husband was nothing if not highly respected within the community.
