From the medieval French name Yolande
, which was probably a form of the name Violante
, which was itself a derivative of Latin viola
"violet". Alternatively it could be of Germanic
This name was borne by a 12th-century empress of the Latin Empire in Constantinople, who was originally from Flanders. It was also used by her descendants in the royal families of Hungary (spelled Jolánta
) and Spain (sometimes spelled Violante
). The Blessed Yolanda of Poland was a daughter of Béla IV of Hungary who married a Polish duke. Another notable bearer was a 13th-century countess of Vianden in Luxembourg who joined a convent against her parents' wishes, later becoming the subject of medieval legend.
