After the death of Ubertino, the Marquisate, like so many Frankish baronies, fell into the hands of a woman. The new Marchioness of Boudonitza was his second sister, Isabella, who is included in the above-mentioned circular note, addressed to all the great magnates of Achaia by Charles I of Anjou, the new Prince, and notifying to them the appointment of Galeran d’Ivry as the Angevin vicar-general in the principality. On that occasion, the absence of the Marchioness was one of the reasons alleged by Archbishop Benedict of Patras, in the name of those present at Glarentza, for the refusal of homage to the new bailie[343]. So important was the position of the Marquisate as one of the twelve peerages of Achaia. The Marchioness Isabella died without children; and, accordingly, in 1286, a disputed succession arose between her husband, a Frank settled in the East, and the nearest male representative of the Pallavicini family, her cousin Tommaso, grandson of the first Marquess’s brother, Rubino. The dispute was referred to Guillaume de la Roche, Duke of Athens, in his capacity of bailie of Achaia, before the feudal court of which a question relating to Boudonitza would legally come. Tommaso, however, settled the matter by seizing the castle, and not only maintained himself there, but transmitted the Marquisate to his son, Alberto[344]. The fifth Marquess is mentioned as among those summoned by Philip of Savoy, Prince of Achaia, to the famous Parliament and tournament on the Isthmus of Corinth in the spring of 1305, and as having been one of the magnates who obeyed the call of Philip’s namesake and successor, Philip of Taranto, in 1307[345]. Four years later he fell, at the great battle of the Kephissos, fighting against the Catalans beneath the lion banner of Walter of Brienne[346], who by his will a few days before had bequeathed 100 _hyperperi_ to the church of Boudonitza[347].
