Supposedly, Rogerio's descendants would then have remained in Casalsottano until 1571, when Giovanni Paleologo was given the fief of Perito and Ostigliano in Salerno. Giovanni's descendants then supposedly remained in Salerno, where they gave rise to the modern (and extant) "Paleologo Mastrogiovanni" (or just "Mastrogiovanni") family, named in his honour.' This family history derives mainly from oral tradition, with only a handful of documents possibly verifying parts of it as true. There is a document from Casalsottano, dated 24 June 1441, which bears the signature of "Ruggerio Greco", "Greco" interpreted by proponents of the Mastrogiovanni descent as a nickname due to his Greek origin rather than a surname. A 1455 document in which Cardinal Isidoro Ruteno grants indulgences to those who donate to a church in San Mauro Cilento mentions a "Ruggerio" as the son of "Tommaso Paleologo". A 1463 document supposedly signed by King Ferdinand I of Aragon records the granting of some lands in the vicinity of San Mauro to Rogerio, son of "illustrissimi Thomae Palaeologi dispoti Moreae". Though most of these documents do not appear questionable in of themselves, they have not been authenticated and there are several problems with the overall reconstruction of events and descent.'
