Career
His will was disputed by his family, and Claudine went to Paris in 1653 to secure its fulfilment. She sought the protection of François de l"Hôpital, marshal of France, then a man of seventy-five. They had one son (c 1654 – c 1657).
In the testament, written on 12 December 1672 in Nevers, John Casimir called himself her debtor.
They had one daughter Marie Catherine (1670 - after 1672), to whom her father left fifteen thousand livres, and asked her to join the Order of the Visitation of Holy Mary. She retired in her old age to a Carmelite convent in the city, where she died on 30 November 1711.
Her history, very much modified, was the subject of a play by Bayard and Paul Duport, Marie Mignot (1829).
