[1] Blanche was born in 1313, before either of her parents ascended their respective thrones, during the reign of her paternal grandfather, King Philip IV of France.
The marriage of her parents was successful enough for her father to insist on her mother's acquittal, but her aunts were imprisoned.
[2] By the time Blanche was seven years old, her parents had become king and queen of France and Navarre and count and countess palatine of Burgundy.
Queen Joan decided that her youngest daughter should join the Order of Saint Francis, probably wishing that the girl's cloistered life could compensate for the sins of her imprisoned namesake aunt.
[5] She is presumed to have at some point owned a richly decorated Franciscan breviary, the earliest known work of Jean Pucelle.
