Origin
The surname NOTARGIACOMO originated in Italy during the medieval period. It is believed to have roots in the southern regions of the country, particularly in the areas around Naples and Calabria. The name itself is thought to be derived from a combination of the Italian words "notaro" and "giacomo," which translate to "notary" and "James," respectively.
One of the earliest recorded instances of the NOTARGIACOMO surname can be found in a document from the 14th century, which mentions a certain Guglielmo NOTARGIACOMO, who was a notary in the city of Naples. This suggests that the name may have originated as a occupational surname, given to those who worked as notaries or scribes.
In the 15th century, there are records of a family bearing the NOTARGIACOMO name residing in the town of Cosenza, in the region of Calabria. This family is believed to have played a significant role in the local community, with some members serving as government officials and landowners.
One notable figure bearing the NOTARGIACOMO surname was Francesco NOTARGIACOMO, who lived in the 16th century and was a prominent lawyer and scholar in Naples. He is known for his contributions to the field of law and his writings on legal theory.
Another individual of historical significance was Giovan Battista NOTARGIACOMO, born in 1602 in the town of Reggio Calabria. He was a renowned painter and fresco artist, known for his works in churches and palaces throughout southern Italy.
In the 18th century, a member of the NOTARGIACOMO family, Antonio NOTARGIACOMO (1726-1798), gained recognition as a composer and musician. He served as the music director for several prominent churches in Naples and composed numerous sacred works.
Throughout history, the NOTARGIACOMO surname has been associated with various places in southern Italy, including towns and villages that bear similar names, such as Notargiacomo di Montalto Uffugo and Notargiacomo di Corigliano Calabro.
While the NOTARGIACOMO surname is not as widespread as some other Italian surnames, it has left its mark on the cultural and historical tapestry of Italy, particularly in the southern regions where it originated and flourished.
Demographics
Among Census respondents with the surname Notargiacomo, the largest self-reported group is White at 89.4%. The next largest groups are Hispanic (5.8%) and Asian/Pacific Islander (1.9%).
The bar chart below shows how Notargiacomo 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 Notargiacomo surname at the time of the 2020 Census, not any inherent property of the name itself.
