Beauvais was born in New Orleans, Louisiana. All of the wands she produced were made from swamp mayhaw wood. For many years, she kept the core she used in her wands a closely-guarded secret, but it was eventually discovered to be rougarou hair. Beauvais's wands were often accused of having a natural affinity for Dark magic. However, many great American wizards of the 1920s used Beauvais-made wands, including President Seraphina Picquery.
