The history of the last name DiTommaso

The surname DiTommaso has its origins in Italy, with records dating back to the 12th century. It is believed to have originated from the medieval Italian personal name "Tommaso," which is derived from the ancient Aramaic name "Toma," meaning "twin." The prefix "Di" was commonly added to surnames in Italy to indicate lineage or place of origin.

One of the earliest recorded instances of the surname DiTommaso can be found in a 13th-century manuscript from the city of Naples, which mentions a nobleman named Guglielmo DiTommaso. This suggests that the name may have originated in the southern regions of Italy, particularly around the Campania region.

During the 14th century, the surname DiTommaso appeared in various records from the city-states of Florence and Siena in Tuscany. This indicates that the name had spread to central Italy by this time. In a 1372 document from the Florentine archives, a merchant named Giovanni DiTommaso is mentioned, suggesting that the name was associated with the prosperous merchant class.

In the 15th century, the name DiTommaso gained prominence in the city of Venice, where several members of the family held influential positions within the powerful Venetian Republic. One notable figure was Marco DiTommaso, a renowned diplomat and ambassador who was born in 1418 and served the Republic until his death in 1492.

As the centuries progressed, the DiTommaso surname spread across Italy and beyond. In the 18th century, a branch of the family settled in the island of Corsica, where they became landowners and influential figures in local politics. One notable Corsican with this surname was Pasquale DiTommaso, a military leader who fought against French occupation in the late 18th century.

Another prominent figure bearing the DiTommaso name was Giuseppe DiTommaso, an Italian sculptor and architect born in Naples in 1828. He was renowned for his work on several churches and public buildings in his native city, and his sculptures can still be seen adorning various landmarks in Naples.

During the 19th and early 20th centuries, many Italians with the surname DiTommaso immigrated to the Americas, particularly to the United States and Argentina, seeking better economic opportunities.
