What does the name Rosalia mean?
Rosalia is a Latin name taken from rosalia, the Roman festival of roses, held on various dates but mainly in May. Both go back to Latin rosa, rose. Wiktionary describes Rosalia as a Latin saints' name, and Rosalie as its French form. In medieval Europe a separate name, Rose, came partly from Germanic elements, as DMNES explains, before it was linked with the flower.
