Origin
Meaning and origin of Repaci
The surname REPACI has its origins in Italy, specifically in the regions of Sicily and Calabria. It is believed to have emerged during the 14th century, derived from the Italian word "repacco," which referred to a type of basket or container used for carrying goods.
In its earliest recorded instances, the name appeared as "Repacchi" or "Repacco" in various historical records and documents from the medieval period. These early spellings likely reflected the regional dialects and variations in pronunciation at the time.
One of the earliest known references to the name REPACI can be found in a collection of notary records from the city of Reggio Calabria, dating back to the late 15th century. These records document transactions and legal agreements involving individuals with the surname Repacchi or Repacco.
As the name spread and evolved over time, various place names and locations became associated with it. For instance, the town of Repacchi in the province of Reggio Calabria is believed to have derived its name from families bearing the REPACI surname who settled in the area.
Among the notable individuals who have carried the REPACI surname throughout history are:
1. Vincenzo Repaci (1540-1612), a renowned Italian painter from Calabria known for his religious works and portraiture.
2. Girolamo Repaci (1629-1692), a Sicilian jurist and legal scholar who authored several influential treatises on canon law.
3. Maria Antonia Repaci (1773-1849), a prominent philanthropist and benefactor from Reggio Calabria, whose charitable contributions helped establish educational institutions and aid the underprivileged.
4. Giuseppe Repaci (1856-1923), an Italian politician and statesman who served as a member of the Chamber of Deputies and held various ministerial positions in the early 20th century.
5. Antonio Repaci (1908-1995), a celebrated sculptor and artist from Sicily, renowned for his monumental public works and religious sculptures adorning churches throughout Italy.

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.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
