Here is a usage example, taken from a record for the Wife of a 3rd great uncle of my wife.Scholastique Thibault (thibaud, Thibeault, Thibeau, Thibaut) in the Web: Québec City Area, Marriage Contract Index, 1761-1940Name: Scholastique Thibault (thibaud, Thibeault, Thibeau, Thibaut) Gender: Female Spouse: Joseph Paradis Marriage Date: 12 Jun 1834 Marriage Place: Quebec, Canada URL: Ancestry.
Scholastique is also the French form of the male name Scholasticus.As such, Scholastique really is a unisex name in France - though probably far more common for girls than for boys.Also, the name can also be variantly spelled Scolastique.
Scholastique of Champagne (d. 1219) was a daughter of Henry I of Champagne and Marie of France, a daughter of Eleanor of Aquitaine. I found it odd that she was given this name, as it's an unusual name among medieval royalty, despite the saint association, and medieval royalty usually reused the same names.
