Teucinde was a woman of the Burgundian aristocracy who followed Hugues d'Arles to Provence and belonged to the family of the counts of Cavaillon.
She was the daughter of the Count of Apt, known by the nickname of Griffon,[a] appointed by King Conrad I of Burgundy in 948 or 949.
A very pious woman, whom some texts describe as a sancto monialis or Deo devota,[c] Teucinde distributed her goods to the religious communities of Arles under the archbishops of Arles, Manasses and Ithier.
On 7 October 949, she bought the island of Montmajour,[d] which belonged to the archbishopric of Arles, and donated it to the Benedictine monks who lived there.
On 19 July 973 Teucinde obtained from Archbishop Ithier the concession of Saint-Hippolyte near Arles for her and her nephew Riculf,[e] Bishop of Fréjus.
