The history of the last name DeJohn

The surname DeJohn has its origins in Italy, where it first emerged in the late medieval period around the 13th or 14th century. It is believed to have originated as a patronymic name, derived from the given name Giovanni, which is the Italian equivalent of the name John. The prefix "de" may have been added to indicate the place of origin or residence of an individual with the name Giovanni.

One of the earliest recorded instances of the name DeJohn can be found in historical records from the city of Naples, where a family by that name is mentioned in documents dating back to the 15th century. These records suggest that the DeJohns were a prominent merchant family involved in the city's thriving trade with other Mediterranean ports.

As the name spread throughout Italy, various spelling variations emerged, such as DeGiovanni, DeGianni, and DeGioan. These variations were likely influenced by regional dialects and the particular scribes who recorded the names.

In the 16th century, the DeJohn name appears in records from the city of Genoa, where a prominent merchant named Antonio DeJohn (c. 1520-1585) is recorded as having established trade connections with the Ottoman Empire. His son, Giacomo DeJohn (1560-1628), is also noted for his role in the city's maritime affairs.

Another notable figure bearing the DeJohn surname was Pietro DeJohn (1685-1754), a renowned architect from the city of Milan. He is credited with designing several notable churches and palaces in the Baroque style, including the Church of San Carlo al Corso in Milan.

As Italians began immigrating to other parts of the world, the DeJohn name spread further afield. In the 19th century, records indicate that a family by the name of DeJohn settled in the United States, where they established themselves in the city of Philadelphia.

Among the more recent historical figures with the DeJohn surname is Mario DeJohn (1901-1987), an Italian-American artist and sculptor known for his distinctive works in bronze and marble. His sculptures can be found in various public spaces and museums across the United States.

Throughout its history, the DeJohn surname has maintained its connection to its Italian roots, reflecting the cultural and linguistic heritage of those who bore this name over the centuries.
