I am researching the surname, SERIO, >from Italy, possibly Sicily.The surname "Serio" is mostly attested in Sicily today. Jews were an high
percentage of the population of the island in the Middle Ages but Jews were
expelled >from Sicily in 1492.
After the expulsion of 1492 some Jews converted and secretly practiced
Judaism (Anusim). But Jews could not live in Sicily for five hundred years:
today all Serios of Sicily are not Jews.
The surname "Serio" is attested as a Jewish surname in Tuscany in the 18th
