GUY de la Roche, son of OTHON [I] de la Roche Lord of Athens & his first wife --- (-1263, bur Daphni). His parentage is confirmed by both the Chronicle of Alberic de Trois Fontaines and the charter dated 19 Apr 1251 quoted below. He succeeded his father as Lord of Athens. The Chronicle of Alberic de Trois-Fontaines records in 1236 that "Guidone duce Atheniensium filio...Ottonis de Rupe Burgundi" created “duo archiepiscopatus, Atheniensis cum episcopo de Argis et archiepiscopus Thebanus cum episcopo de Negrepont”[265]. “Othes de la Roche sires de Rail” confirmed having sold “le chastel d’Argues et le chastel de Naples” to “monseignor Guion de la Roche seignor d’Athenes nostre...frere...madame Agnès dame d’Athènes sa femme”, with the consent of “madame Marguerite nostre femme...et de Guillermete nostre fille, qui est en aage et estoit en presence” and promising to obtain the consent of “Jahan nostre fil qui est en aage et...Isabelon nostre fillie quant ele sera en aage”, in return for rights in Burgundy and Champagne inherited from “monseignor nostre pere et...madame Isabel nostre mere”, by charter dated 19 Apr 1251[266]. He joined the alliance against Guillaume de Villehardouin Prince of Achaia in 1257 to prevent the latter gaining control of the island of Eubœa[267]. Prince Guillaume invaded Athens in 1258, aiming to enforce obedience to Achaia's suzerainty, and defeated Guy at the pass of Mount Karydi. Guy appeared before the High Court of Achaia at Nikli charged with disobedience to his suzerain, but the judges ruled against their own competence to hear the case and submitted the dispute to Louis IX King of France. The French king referred the case to a parliament in Paris which decided that a technical offence had been committed but that the fatigue and expense of the journey to attend the hearing had been sufficient punishment for Lord Guy, who was created GUY I Duke of Athens by the French king in 1260[268]. During the captivity of Guillaume de Villehardouin Prince of Achaia after the battle of Pelagonia in 1259, Guy was appointed bailly of Achaia. “Guis de La Roiche sire d´Athènes” confirmed that he had borrowed funds from “Hugon duc de Bourgoigne” by charter dated Feb 1260 (N.S.)[269]. He opposed the negotiations for Guillaume's release, but was eventually obliged to yield and return power to Guillaume when he returned to Morea in 1261[270]. He agreed an alliance with Ioannes Dukas Komnenos Lord of Thessaly, whose territories were threatened by Emperor Michael VIII, sealed by the marriage of his son with the daughter of the Lord of Thessaly[271].

m AGNES, daughter of --- (-after 19 Apr 1251). “Othes de la Roche sires de Rail” confirmed having sold “le chastel d’Argues et le chastel de Naples” to “monseignor Guion de la Roche seignor d’Athenes nostre...frere...madame Agnès dame d’Athènes sa femme” by charter dated 19 Apr 1251[272]. Her family connections are indicated by the Istoria of Marino Sanudo Torsello which records that "Il principe Guglielmo" brought "di Campagna et Borgogna tre sue nipoti" and that he married the first "al Signor della Rozia", adding that the couple had three sons and three daughters[273]. Her exact relationship with the Villehardouin family has not been ascertained.

 Duke Guy & his wife had [six] children:
