Catherine of France, Countess of Montpensier

Catherine of France was born in Paris on 4 February 1378 as the ninth child and fifth daughter of Charles V, King of France ("Charles the Wise") and his wife Queen Joanna of Bourbon. Catherine had had eight older siblings, only two or three of whom were still alive at the time of her birth: the Dauphin Charles (born 1368), Louis of Orleans (born 1372) and maybe John (born 1375). Her mother Queen Joanna died while delivering Catherine, which deeply upset her father. King Charles V himself died only two years later in 1380, making Catherine's oldest living brother, the 12 year old Dauphin Charles, succeed their father as King Charles VI of France.

In 1386, at the age of eight, Catherine married John of Berry, Count of Montpensier, also known as John of Valois, who was between the ages of nine and eleven. He was the oldest living son and heir of John, Duke of Berry ("John the Magnificent"), and Catherine's first cousin through their shared descent from John II, King of France.

In November 1388, Catherine died at the age of 10 of unknown causes. Her death meant that only two of King Charles V's nine children survived to adulthood and produced offspring: the reigning Charles VI, King of France (who would become the ancestor of the main line of successive Valois kings) and Louis I, Duke of Orléans (who would become the ancestor of the Valois-Orleans cadet branch). As Catherine was only a child at her death, she was unable to have any children with her husband the Count of Montpensier. Two years later Catherine's widower married Anne de Bourbon before his own premature death in 1397, predeceasing his father the Duke of Berry.
