The Valaincourt family was indeed represented in the Fourth Crusade, but as the French medievalist Antoine Bon pointed out, there is nothing other than the similarity of the names to link them to the Frankish Morea.

[8] William, a younger brother of the Duke of Athens Guy I de la Roche, also held the region of Damala in the Argolid as a fief, and the two domains became united under the same title.

[9][10] Damala (ancient and modern Troezen) had been captured easily in the first days of the Frankish conquest of the Morea, unlike the neighbouring citadels of Argos and Nauplia, which continued to resist until 1212.

[11] Although the latter were given as a separate fief to the de la Roche dukes of Athens, Damala itself is not mentioned in the lists of barons of Achaea in the French and Greek versions of the Chronicle of the Morea, which date to c. 1228/30.

[10][17] Renaud was probably killed at the Battle of Halmyros in 1311, and his heiress, Jacqueline de la Roche, married Martino Zaccaria in 1327, who was also Lord of Chios and Baron of Chalandritsa, some time before 1325.
