Rosalee is an American spelling of Rosalie, the French form of the Latin Rosalia, from rosa, "rose"; Saint Rosalia is the patron saint of Palermo. The -lee ending matches the look of Everlee and Hadlee, which has helped the old name feel new again in the 2010s. Rosalee first entered the US top 1000 in 2018, peaked at number 788 in 2020 and, after a brief dip in 2023, ranks number 954 among girls' names in 2025.
