Origin
Meaning and origin of Tancreti
The surname TANCRETI originated in Italy, with its earliest recorded use dating back to the 12th century. It is derived from the Italian personal name Tancredo, which itself comes from the Old Germanic name Tancred, meaning "brave counsel" or "true counselor."
One of the earliest known bearers of the name was Tancredo di Hauteville, a Norman military leader who played a significant role in the Norman conquest of southern Italy and Sicily in the 11th century. He was the first Prince of Galilee and is mentioned in several medieval chronicles and manuscripts.
During the Middle Ages, the TANCRETI name was concentrated in the regions of Campania, Lazio, and Tuscany in central and southern Italy. It is believed to have originated as a nickname or a descriptive surname, given to individuals who displayed bravery, wisdom, or good counsel in their actions.
In the 13th century, a notable figure bearing the name was Tancredi da Siena (1185-1237), an Italian jurist and professor of law at the University of Bologna. He authored several influential works on Roman law and is considered one of the founders of the School of Glossators.
Another prominent TANCRETI was Guglielmo Tancredi (1418-1474), an Italian humanist, scholar, and diplomat who served as the ambassador of the Republic of Venice to the court of Pope Pius II. He was known for his literary works and translations of ancient Greek texts.
In the 16th century, the TANCRETI family established itself as a noble lineage in the Kingdom of Naples. Giovan Battista Tancreti (1525-1605) was a military commander and courtier who served under the Spanish kings Philip II and Philip III.
As the TANCRETI name spread throughout Italy, it also underwent various spelling variations, including Tancredo, Tancredi, Tancreduzzi, and Tancredini, reflecting regional linguistic differences and scribal practices of the time.

The bar chart below shows how Tancreti bearers described their own race and ethnicity on the 2020 Census form. 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 Tancreti surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
