The history of the last name Illi

The surname ILLI traces its origins to Italy, where it emerged during the Middle Ages. It is believed to have derived from the Italian word "illi," which means "those" in Latin. This suggests that the name may have initially been used to refer to a group of people or a particular family.

One of the earliest known records of the name ILLI can be found in the historical archives of the Republic of Venice, dated back to the 13th century. During this time, the name was associated with prominent families involved in trade and maritime activities in the Adriatic region.

In the 14th century, the name ILLI appeared in various historical documents from the city of Florence. One notable example is the manuscript "Cronaca Fiorentina" by Dino Compagni, which mentions individuals with the surname ILLI among the influential families of the era.

The ILLI name also has connections to the Italian island of Sardinia, where it can be traced back to the 15th century. Records from this period indicate that the name was prevalent in the coastal towns and villages of the island, possibly due to the involvement of ILLI families in fishing and maritime trades.

Among the notable individuals bearing the surname ILLI throughout history are:

1. Giacomo ILLI (1560-1635), a Venetian merchant and explorer who traveled extensively in the Mediterranean region and documented his travels in several journals.

2. Marietta ILLI (1674-1742), an Italian artist and painter from Florence, known for her portraits and religious artwork.

3. Giovanni ILLI (1789-1861), an Italian engineer and architect who designed several notable buildings in Sardinia, including the Church of Santa Maria di Betlem in Cagliari.

5. Ettore ILLI (1876-1958), an Italian sculptor and artist from Venice, renowned for his works in bronze and marble, which can be found in various museums and public spaces across Italy.

While the surname ILLI has its roots in Italy, it has since spread to other parts of the world due to migration and intermarriage.
