Simon de Dreux

Simon de Dreux (c. 1300 – after 1326) was a younger son of John II, Count of Dreux, and Jeanne de Beaujeu, Lady of Montpensier. He entered the Church and became sub-dean of Chartres Cathedral, a title recorded for him in a charter of 1326.

Family settlement charters of 1318 and 1320 name him with his brothers Robert, John and Peter, and he was still living in 1326. He held no share of the county, while his three brothers succeeded one another as counts of Dreux.
