Origin
Meaning and origin of Piegaro
The surname PIEGARO originates from Italy, with its roots tracing back to the medieval period. It is believed to have originated from the small town of Piegaro, located in the province of Perugia, Umbria region. The name is likely derived from the Italian word "piegare," meaning "to bend," suggesting a possible occupational origin for those who worked as blacksmiths or metalworkers.
One of the earliest recorded instances of the PIEGARO surname can be found in the archives of the Comune di Piegaro, dating back to the 14th century. These records detail a family of landowners and merchants who played a significant role in the local economy and politics of the region.
In the 15th century, a notable figure named Giovanni PIEGARO (1412-1478) was a prominent scholar and philosopher who taught at the University of Perugia. His treatises on logic and metaphysics earned him recognition throughout northern Italy during the Renaissance era.
During the 16th century, the PIEGARO family expanded their influence beyond Umbria, with some members relocating to other parts of Italy, such as Rome and Naples. Pietro PIEGARO (1523-1601), a skilled architect, was responsible for designing several churches and palaces in Rome, including the famous Santa Maria in Trastevere.
The 17th century saw the PIEGARO name spread further, with records indicating a branch of the family settling in Venice. Antonio PIEGARO (1627-1698) was a respected merchant and trader who established successful trade routes between Venice and the Ottoman Empire.
In the 18th century, a renowned painter named Girolamo PIEGARO (1712-1789) emerged from the family. His works, which primarily depicted religious scenes and landscapes, adorned churches and noble households throughout central and southern Italy.
As the centuries progressed, the PIEGARO surname continued to be associated with various professions, including law, medicine, and academia. Notable figures from more recent history include Luciana PIEGARO (1892-1967), a celebrated opera singer who performed in major theaters across Europe, and Ettore PIEGARO (1914-1998), a renowned physicist who made significant contributions to the field of quantum mechanics.

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.
