• Married:
• Died: 6 March, between Nov 1035 and 1 Mar 1042

  Research Notes:

Edouard de Saint-Phalle suggests that he was Geoffroy, nepos of Gauthier Comte de Gâtinais, referring to the letter dated to [997] in which Abbon abbé de Saint-Benoît-sur-Loire requested Pope Gregory V to order "…Quauz---, nepos Wal--- comitis de Castro Nantonis" to cease his activities (presumably against the monastery) under threat of excommunication, by letter dated [997]. He bases his theory on the donation dated Nov 1035 by Geoffroy de Joigny's son, Gilduin Archbishop of Sens, to the same abbey.

The necrology of Saint-Etienne, Troyes records the death "6 Mar" of "Gaufridi de Jooigny", although it is not known whether this entry refers to this Geoffroy. ¹
