Andrea is absolutely rare, as well as Andreacci, Andreasi is typical of the Triveneto, Trentino, Verona and Rovigoto, with significant presences also in the Latin area, probably due to the Venetian emigration at the time of the reclamation of the Pontine Marshes, Andreetta, decidedly Venetian from the Treviso area , with significant presences also in Padua and Venice, Andreetti has a lineage in the Ferrara area and one in the province of L'Aquila, Andrei has a stock in the Parma area and in Tuscany, Andreini is typically Tuscan in the provinces of Lucca, Florence and Arezzo in particular, Andreocci is typically Lazio, widespread in Priverno in the latinense, in Vignanello in the Viterbo area and in Rome, Andreoli is widespread throughout the centronord, in northern Campania and Calabria, Andreolo, almost disappeared, would seem to be Venetian, Andreotti is widespread in the north, in upper Tuscany , in the area of L'Aquila, Lazio, Naples and Benevento, Andretti has a stock in the Neapolitan and one in the Foggia area, Andreutti is typical Friulian from Ragogna, Majano and San Daniele from Friuli in Udine and Trieste, Andreutto, very rare, is Venetian, Andriolo has a large Venetian lineage, especially in the Vicenza area and in the Venetian area, an Apulian strain between Bari, Brindisi and Lecce, and a Sicilian lineage, in particular in the Palermo area and in the Messina and Catania areas, Andriulo is typically Pugliese, quite rare, specific to the Brindisi and Taranto areas. All these surnames and many others still have in common the derivation, through dialectal, hypocoristic or particular patronymic forms, from the proper Greek nameAndreas which originates from the Greek andros (man) that we find in the Latin Andreas, who became the Italian Andrea. The antiquity of the name has allowed a homogeneous distribution throughout Italy, even if with different forms. The area of maximum concentration of these surnames is however the north-eastern area.
