The surname Martinelli has its roots in Italy, originating in the medieval period. It is a patronymic name derived from the personal name Martino, which is the Italian form of the Latin name Martinus. This name ultimately traces its origins back to the Roman god Mars, the god of war.
The Martinelli surname first emerged in the regions of Tuscany and Lombardy, where it was particularly prevalent. It is believed that the name may have been associated with the trade of blacksmithing or metalworking, as these professions were often linked to Mars, the god of war.

In the 14th century, the name appears in the historic chronicles of the city of Siena, where a Guido Martinelli is documented as a prominent citizen.
During the Renaissance period, the Martinelli family gained prominence in various Italian cities. In the 15th century, a notable figure was Antonio Martinelli (1445-1515), a renowned architect from Siena who designed several churches and palaces in his hometown.
Another notable Martinelli was Vincenzo Martinelli (1590-1659), a Jesuit scholar and historian from Genoa. He authored several works on the history of the Jesuit order and the lives of saints.
In the 18th century, Sebastiano Martinelli (1701-1777) was a celebrated mathematician and astronomer from Bologna. He made significant contributions to the field of celestial mechanics and was a member of the prestigious Accademia delle Scienze dell'Istituto di Bologna.
The Martinelli surname also gained prominence in the arts. In the 19th century, Giuseppe Martinelli (1833-1887) was a renowned Italian painter from Naples, known for his depictions of historical and religious scenes.

Demographics
Among Census respondents with the surname Martinelli, the largest self-reported group is White at 89.7%. The next largest groups are Hispanic (5.9%) and Two or More Races (2.6%).
The bar chart below shows how Martinelli bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Martinelli surname at the time of the 2020 Census, not any inherent property of the name itself.
