Here is a recapitulation of our material.
"Gilles de Rais was born about 1404 on the boundary between Brittany and Anjou, in the chateau de Machecoul.

We know nothing of his childhood.
His father died about the end of October, 1415, and his mother almost immediately married a Sieur d'Estouville, abandoning her two sons, Gilles and Rene.

They became the wards of their grandfather, Jean de Craon, 'a man old and ancient and of exceeding great age,' as the texts say.

He seems to have allowed his two charges to run wild, and then to have got rid of Gilles by marrying him to Catherine de Thouars, November 30, 1420.
"Gilles is known to have been at the court of the Dauphin five years later.

His contemporaries represent him as a robust, active man, of striking beauty and rare elegance.
