Many Byzantine refugees, though unrelated to the emperors, legitimately bore the name Palaiologos due to the extensive nature of the family. Because the name could lend whoever bore it prestige (as well as possible monetary support), many refugees fabricated closer links to the imperial dynasty. Many Western rulers were conscious of their failure to prevent Byzantium's fall and welcomed these men at their courts. The refugees were helped in that many in Western Europe would have been unaware of the intricacies of Byzantine naming customs; to Western Europeans, the name Palaiologos meant the imperial dynasty. Though such Palaiologoi, imperial or not, were mainly concentrated in northern Italy, such as in Pesaro, Viterbo or Venice, other Greek refugees travelled across Europe, many ending up in Rome, Naples, Milan, Paris or in various cities in Spain.
