Origin
The surname Tempero is of Portuguese origin, originating in the 14th century in the region of Minho, northern Portugal. It is derived from the Portuguese word "temperar," which means "to season" or "to temper," referring to the occupation of a spice merchant or someone involved in the preparation and seasoning of food.
The earliest recorded instances of the Tempero surname can be found in historical documents from the late 14th century, such as municipal records and parish registers in the towns of Braga and Guimarães. These early records often featured variations in spelling, including Tempeiro, Tempeyro, and Tempero.
In the 16th century, a prominent figure bearing the Tempero surname was João Tempero, a renowned spice trader from Porto who established trade routes with the Middle East and Asia, importing exotic spices and herbs into Portugal. His legacy as a successful merchant contributed to the association of the name with the spice trade.
Another notable individual was Sebastião Tempero (1570-1635), a Portuguese explorer and navigator who participated in several expeditions to the East Indies and the Moluccas. His accounts and maps from these voyages provided valuable insights into the region's geography and trade routes.
During the 17th century, the Tempero surname gained prominence in the Azores archipelago, where several families settled and established themselves as landowners and merchants. One such individual was Manuel Tempero (1620-1688), a wealthy landowner and trader from the island of Terceira, known for his philanthropic contributions to the local community.
In the 19th century, a celebrated figure was Antónia Tempero (1815-1892), a Portuguese writer and educator from Lisbon. She authored several books on education and literature, advocating for women's rights and educational opportunities.
Another notable Tempero was João Tempero (1845-1918), a prominent architect from Porto who designed several iconic buildings in the city, including the Palácio da Bolsa (Stock Exchange Palace) and the Igreja dos Clérigos (Clerigos Church).
Throughout its history, the Tempero surname has been associated with various professions, including spice traders, merchants, explorers, landowners, writers, and architects, reflecting the diverse backgrounds and contributions of those who carried this name.
Demographics
Among Census respondents with the surname Tempero, the largest self-reported group is White at 93.3%. The next largest groups are Two or More Races (3.8%) and Black (1.9%).
The bar chart below shows how Tempero 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 Tempero surname at the time of the 2020 Census, not any inherent property of the name itself.
