Origin
The surname EFIGENIO is of Greek origin, derived from the Greek word "efigéneia," which means "noble birth" or "high-ranking descent." This surname likely emerged during the Byzantine Empire, which ruled over parts of Greece from the 4th to the 15th centuries.
The earliest known records of the EFIGENIO surname can be traced back to the 11th century, when it appeared in Byzantine chronicles and documents referring to noble families in the region of Thessaly, located in central Greece. It is believed that the name was initially adopted by individuals of noble or aristocratic lineage to signify their distinguished heritage.
During the medieval period, the EFIGENIO surname was particularly prominent among the Greek nobility and ruling classes. Historical records from the 13th century mention a notable figure named Ioannis Efigenio, who served as a high-ranking military commander under the Despotate of Epirus, a Byzantine Greek successor state in northwestern Greece.
In the 15th century, as the Byzantine Empire was declining, many Greek families bearing the EFIGENIO surname sought refuge in other parts of Europe, particularly Italy and the Venetian-controlled territories. This migration contributed to the spread and diversification of the surname across the Mediterranean region.
One of the earliest known bearers of the EFIGENIO surname in Italy was Georgios Efigenio, a scholar and philosopher born in the late 15th century in the city of Corfu, then under Venetian rule. He later settled in Venice and became renowned for his writings on Greek philosophy and culture.
Another notable individual with the EFIGENIO surname was Alexandros Efigenio, a Greek merchant and diplomat who lived in the late 16th century. He was instrumental in facilitating trade and diplomatic relations between the Republic of Venice and the Ottoman Empire, which controlled parts of Greece at the time.
In the 18th century, a branch of the EFIGENIO family settled in the Ionian Islands, then under Venetian and later British rule. Spyridon Efigenio, born in 1765 on the island of Zakynthos, was a prominent figure in the Greek War of Independence against the Ottoman Empire in the early 19th century.
As the EFIGENIO surname spread across Europe and the Mediterranean region, it underwent various spelling variations, such as Efigenios, Efighenio, and Efigheneio, reflecting the local linguistic influences and dialects of the regions where the surname was adopted.
Demographics
Among Census respondents with the surname Efigenio, the largest self-reported group is Hispanic at 89.0%. The next largest groups are White (6.8%) and Two or More Races (2.5%).
The bar chart below shows how Efigenio 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 Efigenio surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
