Hi. My name is Megan Liprie and I live in southwest LA. I don't know if this information will help you. I have been doing research on my grandmother's family and her mother's maiden name was Darbonne. Her mother's gg grandmother was Catherine Josette Donato. Catherine's parents were Donato Bello and Marie Jeanne Tailefero, who was a mulatresse of New Orleans. Catherine's brother, Martin Donato Bello, married Marianne Duchesne and had a daughter name Marie Denyse Donato. Marie married Francois Lemelle and had a daughter name Euphemie Lemelle. Euphemie married a man named Charles Lemelle and had a son name Charles Lemelle. I don't know if this will help you but after reading your query, I knew that I had information about the Lemelle family. Good luck to you on your search!
