Jacquette de Grandson
Jacquette de Grandson (1312–1378 or 1381) was the daughter of Peter II of Grandson and Blanche of Savoy-Vaud. She married Girard de Montfaucon, lord of Orbe and Échallens in the Vaud country.
In 1351 the couple granted town franchises to Orbe and Échallens to repopulate their lands. After her son Jean III died without legitimate children in 1372, Jacquette kept the usufruct of the Montfaucon inheritance until her death.
