Ursion (Orson) I DE NEMOURS Seigneur de Château-Landon

   General Notes:

His possible parentage is suggested by Richemond, based on the proximity of Nemours to Château-Landon, but he emphasises that there is no primary source which confirms that it is correct. Richemond assumes that Urson was the first Seigneur de Nemours but states that there is no record of him either in contemporary chronicles or cartularies, although he adds that he and his son Hervé left on the Second Crusade in 1147 and both died during the expedition (without citing the corresponding primary source).

   Marriage Information:

Ursion married Aveline DE MONTFAUCON, daughter of Renaud DE MONTFAUCON-EN-BERRY and Elisabeth DE GIEN.
