Isobel Derant

Isobel Derant (1538-1557) was a French heretic and the cousin of Sebastian de Poitiers.

Biography[]

Isobel Derant was born in 1538, the daughter of Jonathan Derant. Her father, the half-brother of Diane de Poitiers, was executed in 1543 after participating in a heretic uprising against the King, and, in 1557, shortly after her husband was also executed, she was arrested by King Henry II of France's guards after she was accused of theft. Her cousin Sebastian de Poitiers, who had become regent of France during Henry's absence in Rome, had her held in the castle as her home was searched, and he later attempted to help her escape due to his family ties to her; Queen Catherine de Medici attempted to expose Sebastian's relationship with Isobel in order to discredit him. While Sebastian and Mary, Queen of Scots helped Isobel in fleeing into the woods, she died in childbirth while giving labor there.
