Origin
The surname PROFENNO is believed to have originated in the region of Sardinia, an island off the western coast of Italy. The name can be traced back to the 11th century, with the earliest known records dating from around 1050 AD. It is thought to be derived from the Latin word "profundus," meaning deep or profound, possibly referring to a deep valley or ravine where the family may have resided.
In the medieval period, the name PROFENNO appeared in various forms, including Profennu, Profenni, and Profennio. These variations were likely due to differences in regional dialects and spelling conventions of the time. One of the earliest known references to the name can be found in a 12th-century manuscript from the Archivio di Stato di Cagliari, which mentions a landowner named Iohannes Profenno.
By the 13th century, the PROFENNO family had established themselves as minor nobility in the region of Barbagia, in the mountainous interior of Sardinia. Records from this period mention several individuals bearing the name, including Gonnario Profenno, a local magistrate who lived in the late 1200s, and Antonia Profenno, a noblewoman who inherited a sizable estate in 1289.
In the 15th century, the PROFENNO name gained prominence with the birth of Salvatore Profenno (1432-1498), a renowned scholar and poet who was widely celebrated for his works in the Sardinian language. Another notable figure from this time period was Giovannico Profenno (1460-1529), a military commander who served under the House of Aragon during the Spanish control of Sardinia.
As the PROFENNO family spread throughout Sardinia and beyond, the name took on various forms, including Profennone, Profennini, and Profennaro. Some branches of the family adopted place names as part of their surname, such as Profenno di Tonara and Profenno di Bitti, referring to the towns of Tonara and Bitti in central Sardinia.
One of the most famous individuals to bear the PROFENNO name was Giovanni Maria Profenno (1568-1638), a Jesuit priest and missionary who traveled extensively throughout the Americas and wrote several influential works on the indigenous cultures of South America. In more recent times, notable figures with the surname PROFENNO include Antonio Profenno (1823-1901), a Sardinian politician and activist, and Efisio Profenno (1912-1998), a renowned sculptor and artist from the town of Nuoro.
Demographics
Among Census respondents with the surname Profenno, the largest self-reported group is White at 95.0%. The next largest groups are Hispanic (3.3%) and American Indian/Alaska Native (0.8%).
The bar chart below shows how Profenno 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 Profenno surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
