Origin
Meaning and origin of Delauro
The surname DELAURO has its origins in Italy, tracing back to the 13th century. It is believed to have originated from the Italian words "de" and "lauro," which translate to "of" and "laurel," respectively. This suggests that the name initially referred to someone who lived near or was associated with laurel trees.
One of the earliest known references to the name DELAURO can be found in historical records from the city of Naples, where a family bearing this surname was documented in the late 1200s. It is possible that this family had connections to the laurel tree, either through cultivation, trade, or symbolic association.
In the 14th century, the name DELAURO appeared in various manuscripts and records across the Italian peninsula, including the region of Tuscany. During this period, the spelling variations "De Lauro" and "Delauri" were also observed.
One notable individual with the surname DELAURO was Girolamo Delauro, a 16th-century Italian painter and architect born in Naples in 1504. He was known for his works in the Mannerist style and contributed to the design of several churches and palaces in his hometown.
Another significant figure was Alessandro Delauro, born in 1570 in Siena, Tuscany. He was a renowned scholar and author who wrote extensively on topics ranging from philosophy to linguistics. His works were widely recognized and influential during the Renaissance period.
In the late 17th century, a branch of the DELAURO family settled in the region of Calabria, where they became prominent landowners and merchants. One member of this branch, Giovanni Battista Delauro (1693-1768), was a respected magistrate and legal scholar who served in the local courts.
The name DELAURO also appeared in historical records from the region of Abruzzo, where a family bearing this surname was documented in the 18th century. Among them was Antonio Delauro (1722-1798), a celebrated poet and playwright whose works were widely acclaimed during his lifetime.
Throughout the centuries, the DELAURO surname has been associated with various prominent individuals across different regions of Italy, including scholars, artists, and legal professionals. While its origins can be traced back to the 13th century, the name continues to be carried on by families worldwide, reflecting its rich historical heritage.

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.

Does the Census include every surname?
