Sphrantzes in his Short History mentions a Kydonides Tzamblakon next to Thomas Palaiologos, that he calls the most beloved uncle of his wife. In 1459, this man aroused Thomas in a war against his brother Demetrios Palaiologos.[4] Kydonides Tzamblakon was married to a sister of Catherine's mother.[1] In Kalavryta there survives a palace known in the region as "the palace of Palaiologina," that according to tradition, was given as a personal gift by Constantine Palaiologos to his sister-in-law Catherine, and as such, received its name from her.[5]
Catherine remained in the Morea as Thomas' consort until the Ottomanconquest in 1460, after which she fled with her husband and children to the Venetian-held island of Corfu. George Sphrantzes acted as a servant of Catherine's household for some time.[6] Eleni Tzamblakina, the wife of Sphrantzes, was a second cousin of Catherine, from the side of her Asenina-Palaiologina mother.[1] She died on 26 August 1462 and was buried in the Monastery of Jason and Sosipatros.[2] The erudite and later professor of the Greek language Hermonymos Georgios wrote an eulogy for Catherine.[7] Hermonymos was close to the family of Thomas. He said that he wrote the epitaph for Catherine not out of duty, but out of his deep admiration for her. In it he laments her death and praises her as "a divine empress" and "the most modest and bravest of women".[8]
