Origin
The surname XEC traces its origins to Catalonia, a region in northeastern Spain, during the medieval period. Catalonia was known for its distinct language and culture, often influenced by a mix of Iberian, Roman, and later influences from the Frankish Empire. The surname appears to have emerged from the area around the cities of Girona and Barcelona in the 12th century.
XEC seems to derive from an old Catalan word xequer, which was a term used to describe a specific form of professional or occupational role, perhaps related to bookkeeping or administration. The medieval Catalan language often employed the suffix -ec or -ec in occupational names, which could explain the formation of XEC from xequer. Similar spellings in old records include Xecre and Secher, indicating potential variations due to phonetic transcription over centuries.
One of the earliest historical references to the surname XEC appears in a 13th-century land grant document preserved in the archives of Barcelona, indicating the presence of a Jordi XEC who owned a parcel of land outside the city in 1274. Another manuscript from 1351 references Marta XEC, a merchant in Girona, who was involved in the trade of textiles, indicating the surname was associated with varied professions.
The surname appears in the records of the Spanish Inquisition in the late 1400s, with Juan XEC noted as a staunch defender of Christian teachings against the spread of other religious influences. He was an influential figure in his community, born circa 1440 and dying in 1506.
Throughout the 16th and 17th centuries, the surname XEC can be found in ecclesiastical records. Notably, a priest named Pere XEC, born in 1510, is mentioned in monastery records and recognized for his contributions to the translation of religious texts into Catalan. Pere XEC lived a long life, passing away in 1580.
In the realm of literature, the 18th-century poet Ricard XEC of Barcelona gained some renown. Born in 1725, Ricard was known for his lyrical works that celebrated the Catalan landscape and cultural heritage. His work, while not widely known today, was influential in the literary circles of his time. Ricard XEC died in 1789.
Entering the 19th century, the revolutionary fervor in Europe saw the involvement of the XEC lineage yet again. Francesca XEC, born in 1802, was a noted activist advocating for Catalonian independence from Spanish rule. Her efforts and speeches left a significant legacy in the regional archives before her death in 1865.
By connecting these references, the surname XEC emerges as a historical marker of Catalonian heritage, representative of varied professional roles, cultural contributions, and revolutionary spirit over the centuries. The name continues to hold historical significance in the context of Catalan history and culture.
Demographics
Among Census respondents with the surname Xec, the largest self-reported group is Hispanic at 97.8%. The next largest groups are White (0.5%) and Black (0.5%).
The bar chart below shows how Xec 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 Xec surname at the time of the 2020 Census, not any inherent property of the name itself.
