Italians in Poland around 1500-1600's

Does anyone know of Italian's migrating to Poland in 1500-1600's?
My grandfather was a Data and I have been told more than once that it is of Italian origin. Specifically in Northern area near Turin - Piedmont region. There are many Data's in Forno Canavese and there is a hamlet or frazione called Data.

Bona Sforza(1493-1557), became the second wife of Sigismund I the Old, the King of Poland and Grand Duke of Lithuania, and became the Queen of Poland and Grand Duchess of Lithuania, in 1518.

She brought with her many Italians, others followed suit - cooks, gardeners, artists, architects ...

Here is for example a signed cameo, bearing the signature of Gian Giacomo Caraglio (1500/1505-1565). Best known as a printmaker, Caraglio who was born in Vienna and later worked in Venice and then Kraków, metmuseum.org/toah/works-of-art/17.190.869.

Excerpts translated from a website of Italian Embassy in Warsaw:
In the fifteenth century, through contacts with various Italian universities, cooperation in cultural level clearly developed between the two countries: many Polish students, including Nicolaus Copernicus, completed their studies in Italy, while Italian teachers often came to Poland to educate children of the Polish nobility. Through such contacts, favorable to popularization of the idea of humanism and the Renaissance, the Italian influence on Polish art and culture lasted for over three centuries.

And since the nineteenth century, thanks to the contacts between patriots of both countries, gave a new momentum to mutual relations: between 1848 and 1849, many Polish soldiers conscripted into the ranks of Savoie troops, fought alongside Piemont soldiers in the first War of Independence. Many Poles also fought in defense of the Roman Republic, while others participated in the Expedition of the Thousand.

It is the common ideals of freedom and the brotherhood in arms, which have brought the two nations together in the struggle for national liberation against the domination of foreign powers. Even the famous poet Adam Mickiewicz fought for the independence of Italy, and garibaldini Francesco Nullo and Stanislao Becchi participated in the fighting on Polish soil.
