In addition to the John Palaiologos of the Pesaro genealogy, some Italian genealogies from the 17th century onwards ascribe further sons to Thomas Palaiologos, notably a supposed older son by the name Rogerio or Ruggerio. According to the genealogies, Rogerio would have been born about 1430 and was supposedly sent to Alfonso the Magnanimous of Aragon and Naples as a hostage to guarantee some treaty with the Byzantines. Supposedly, he is to have stayed in Casalsottano, a hamlet of the Italian "comune" San Mauro Cilento, in a 15th-century building commonly referred to as the "Palazzo" ("the palace"). His stay in Casalsottano is said to have attracted Byzantine refugees of other families, such as the Notaras and Komnenoi, to the hamlet in the aftermath of Constantinople's fall, and together they supposedly erected the "Spirito Santo" church, which still stands today. Rogerio was purportedly a judge and is said to have died in 1488,' survived by his wife Antonia and his two children John (or Giovanni) and Angela.'
