People/CharactersMarie de Castelnau, Madame de la Mauvissiere

Marie de Castelnau (née Bochetel) was the much younger wife of Michel de Castelnau, Sieur de la Mauvissière (c. 1520 – 1592), French soldier and diplomat, ambassador to Queen Elizabeth.  She married him around 1575, at the time that he was sent to England.  During the first six years, they had two sons and two daughter: Elisabeth and Katherine-Marie.  Around 1581, she took the children and went to France.  In the summer of 1583, she returned to England, leaving the boys in France.  She then had a series of miscarriages and unhappy pregnancies.  She died in childbirth in 1586, just after their return to France.
