Origin
Meaning and origin of Amplo
The surname Amplo has its origins in Italy, tracing back to the 13th century. It is believed to have derived from the Italian word "amplo," which means "ample" or "expansive." This suggests that the name may have initially referred to someone who lived in a spacious or large dwelling or had a generous or magnanimous personality.
The earliest known record of the name Amplo dates back to 1287 in the Tuscan region of Italy, where a nobleman named Giovanni Amplo was mentioned in a historic document detailing land ownership. This indicates that the name was well-established in the area during that time period.
In the 14th century, the name Amplo appeared in several historical records from the city of Florence, including tax rolls and guild registries. One notable figure was Antonio Amplo, a renowned artist and fresco painter who was commissioned to decorate several churches and palaces in the city between 1355 and 1382.
As the name spread across Italy, it underwent slight variations in spelling, such as Amplio and Amplio. In the 16th century, a branch of the Amplo family settled in the coastal region of Liguria, where they became prominent merchants and traders. One member, Giovanni Battista Amplo (1522-1589), was a successful sea captain who sailed to the Americas and established trade routes with the New World.
In the 18th century, the surname Amplo gained recognition in the field of academia. Carlo Amplo (1712-1788) was a celebrated philosopher and mathematician from Milan, who made significant contributions to the study of calculus and was elected to the prestigious Accademia dei Lincei.
Another notable figure was Lucia Amplo (1765-1824), a poet and writer from Naples, whose works explored themes of love, nature, and the human condition. Her collection of sonnets, titled "Amori Ampli," was widely acclaimed and influenced later generations of Italian poets.
Throughout its history, the surname Amplo has been carried by individuals from various walks of life, including artists, scholars, merchants, and nobles, reflecting the diverse backgrounds and achievements associated with this Italian name.

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 Amplo surname at the time of the 2020 Census, not any inherent property of the name itself.
