Nemours is situated in Gâtinais, midway between Fontainebleau and Château-Landon, on the left bank of the river Loing. According to Richemont, Nemours was founded in [1120/30] and started to flourish after a hospice was built to serve the needs of pilgrims who sought allegedly miraculous cures effected by relics which had been transported back from Palestine and housed in the village[2010]. The history of Nemours was studied in detail by Richemond in the early 20th century[2011]. The seigneurie de Nemours lay south of the seigneurie de Milly and north of the vicomté de Château-Landon[2012]. The seigneurs de Nemours were appointed to important positions at the court of Louis VII King of France and members of the family received the highest ecclesiastical honours in the 12th and 13th centuries. However, towards the end of the 13th century they were ruined by participation in the crusades, forced to sell their castles and renounce their positions, and fell into obscurity[2013]. Nemours was sold to Philippe III King of France in 1276 by Philippe [III] de Nemours[2014]. Nemours was elevated into a duché-pairie by Charles VI King of France in 1404. It was first granted to the king of Navarre in exchange for territories in Champagne and Vexin, and was eventually inherited by a younger branch of the family of the Dukes of Savoy. Nemours returned to the French crown in 1666.
URSON, son of [FOULQUES Vicomte de Château-Landon & his wife Biote de Montlhéry] (-[Palestine 1147]). 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[2015]. 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 primarysource)[2016].
m AVELINE de Monfaucon, daughter of --- de Monfaucon & his wife --- [de Châtillon-sur-Loing] ([1110/20]-). Her parentage and marriage are confirmed by the Chronicle of Alberic de Trois-Fontaines which records that "principe Antiochie Renaldo" had a sister who was the mother of "Renaldum de Monte Falconis in Bituria et duas sorores illius", of whom one "Avelina de Traci" married "viro nobili Ursoni"[2017]. Dame de Tracy, which Richemond identifies as Treuzy near Nemours[2018].
