Origin
Meaning and origin of Morroni
The surname Morroni traces its origins to Italy, with evidence suggesting its roots extend back to the medieval period. Specifically, the name is likely derived from the Italian regions of Lazio or Umbria, areas known for their rich history and cultural heritage. The name itself possibly originates from the old Italian word "morro," which describes a hill or mound, indicating that the original bearers of the name might have lived near such geographical features.
Historical records show that the name Morroni appeared in various manuscripts and documents going back several centuries. An early reference can be found in the 14th century, where a Pietro Morroni was recorded as a landowner in the Lazio region, suggesting a degree of prominence and property ownership. Another early record mentions a Domenico Morroni, a merchant from Perugia, in a trade document from the late 1400s, indicating the spread of the surname to different parts of Italy.
The Morroni surname also shows connections to notable historical figures. For instance, Giovanni Morroni, born in 1523, served as a councilor in the city of Viterbo. His contributions to local governance and urban development were well documented in municipal records of the time. Another influential figure was Maria Morroni, an artist born in 1586, whose works contributed to the rich tapestry of Renaissance art in central Italy.
In the 17th century, the name appears again with Francesco Morroni, a scholar born in 1642, known for his writings on natural philosophy and astronomy. His works were published and widely read, underscoring the intellectual legacy carried by the Morroni name. Moving into the 18th century, Luigi Morroni, born in 1715, became known as an influential architect whose designs incorporated elements of Baroque grandeur, leaving a lasting impact on the architectural landscape of Rome.
The 19th century saw the emergence of figures like Alessandro Morroni, born in 1832, who was a revolutionary and activist involved in the Italian unification movement. His efforts were instrumental in rallying support for the cause of a unified Italy, and his legacy is remembered in historical texts detailing the Risorgimento.
Overall, the history of the surname Morroni is replete with individuals who have made significant contributions across various fields, from governance and commerce to art, science, and political activism. The name carries a legacy that highlights a deep connection to Italian heritage and historical development.

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.

Is this page using the latest Census data?
Not necessarily. Morroni appears here with 2000 Census data, while the latest surname file loaded on Name Census is 2020. When a surname drops below the Census publication threshold, older rows can still be kept for historical reference even if the name no longer appears in the newest file.
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
