An important nucleus in the Cosenza area, towards the borders with Basilicata and perhaps another in the Salerno area, should derive from the toponym Regina (CS), but a derivation from the Latin cognomen Reginus, Regina, cannot be excluded.
Regina is typical of the south, of Naples, Mormanno (CS), Grumo Appula (BA), Castel di Lucio (ME), Syracuse and Alcamo (TP), Regini is more than central Italy, Tuscany, Marche and Lazio, with a strain also in the Venetian, Reina would appear to be native to western Sicily, but There are Lombard strains treated apart, Reini is almost unique, derive either directly or from the dialectal form of the Late Latin name Regina (referred to the Madonna = Regina coeli).
