Origin
Meaning and origin of Colannino
The surname Colannino is of Italian origin, specifically from the region of Campania in southern Italy. It is believed to have originated in the late medieval period, around the 14th or 15th century.
Colannino is a diminutive form of the Italian word "colonna," which means "column" or "pillar." This suggests that the name may have originally been given to someone who lived near a prominent column or pillar, or perhaps to someone who worked as a builder or stonemason involved in the construction of columns or pillars.
One of the earliest recorded instances of the name Colannino can be found in the archives of the city of Naples, where a certain Giovanni Colannino was listed as a merchant in the year 1487. Another early reference is from the town of Salerno, where a Giulio Colannino was recorded as a landowner in the 16th century.
During the Renaissance period, several notable individuals bore the surname Colannino. For example, Vincenzo Colannino (1540-1612) was a renowned painter and architect from Naples who worked on various churches and palaces in the city. Another Colannino, Francesco (1572-1638), was a philosopher and theologian who taught at the University of Naples.
In the 17th century, a branch of the Colannino family settled in the town of Aversa, near Naples. One of their descendants, Antonio Colannino (1674-1742), became a respected lawyer and served as a judge in the Kingdom of Naples.
Another prominent figure with the surname Colannino was Pasquale Colannino (1798-1879), a politician and writer from Avellino. He was actively involved in the Italian unification movement and wrote several works on history and literature.
While the surname Colannino is not extremely common today, it continues to be found primarily in the Campania region of Italy and among descendants of families that originated from that area.

The bar chart below shows how Colannino 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 Colannino surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
