Gilles de Rais
The district of Retz or Rais is in southern Brittany, and has been under the control of several different families. Retz always spelled the word "Rais." The barony of Retz first belonged to the House of Retz, then to the Chabot family and the Laval family. Gilles de Rais, a Laval and comrade in arms of Joan of Arc, was executed without an heir, so the barony passed successively to the families of Tournemine, Annebaut and Gondi.
