Dracinia Trousseau (née DeVille) was the daughter of Pascal Chevalier and Fleurette duPrix. Her sisters were Nicole DeVille and Hesperia DeVille. She married Maurice Trousseau and had 3 children: Leo Trousseau, Vinca Trousseau and Daniel Trousseau.
In many cultures it is traditional for the wife to take her husband's surname when she marries, and any children born would also have the husband's surname. However, in The Simpsons Uncensored Family Album, Dracinia and her two sisters are shown as having the surname DeVille. This does not appear to be a middle name and it is unknown what circumstances led to the three children having a different last name than their parents.
