Origin
Meaning and origin of Lopezlopez
The surname LOPEZLOPEZ is of Spanish origin, with roots tracing back to medieval times in the Iberian Peninsula. It is a double-barreled surname, likely formed by the repetition of the common Spanish surname Lopez.
The name Lopez itself is derived from the Latin name "Lupus," meaning wolf. In the Middle Ages, it was common for individuals to adopt descriptive surnames based on physical characteristics, occupations, or places of origin. Lopez may have originally referred to someone with wolf-like traits or someone who lived near a wolf's den.
One of the earliest recorded instances of the surname LOPEZLOPEZ can be found in the "Libro de Repartimiento de Sevilla," a document from the 13th century that recorded the distribution of land and properties in Seville after the Christian reconquest of the city. This suggests that families bearing this surname may have played a role in the Reconquista, the centuries-long campaign by Christian kingdoms to reclaim the Iberian Peninsula from Moorish rule.
During the 15th century, the LOPEZLOPEZ name appeared in various historical records from the region of Castile, including municipal archives and court documents. One notable figure from this era was Juan LOPEZLOPEZ, a prominent merchant and landowner from Valladolid, who lived from approximately 1420 to 1495.
In the 16th century, the LOPEZLOPEZ surname spread across the Spanish Empire, as explorers, soldiers, and settlers embarked on voyages to the Americas and other territories. One such individual was Pedro LOPEZLOPEZ, a conquistador who accompanied Hernán Cortés in the conquest of Mexico in the early 1500s.
As the Spanish Empire expanded, the LOPEZLOPEZ name became associated with various regions and place names. For example, in the late 17th century, Diego LOPEZLOPEZ was a notable landowner and rancher in the region of Nuevo León, in what is now northern Mexico.
Other notable individuals bearing the LOPEZLOPEZ surname include:
1. Francisco LOPEZLOPEZ (1692-1767), a Spanish military officer and explorer who led expeditions to the Pacific Northwest region of North America.
2. María LOPEZLOPEZ (1775-1855), a Venezuelan writer and educator who played a significant role in the independence movement against Spanish colonial rule.
3. José LOPEZLOPEZ (1810-1888), a Mexican politician and landowner who served as governor of the state of Jalisco in the mid-19th century.
4. Emilia LOPEZLOPEZ (1866-1942), a renowned Spanish opera singer and vocal instructor who performed across Europe in the late 19th and early 20th centuries.
5. Raúl LOPEZLOPEZ (1921-2008), a Cuban-American artist and sculptor known for his abstract expressionist works, active in the mid-20th century art scene in New York City.

The bar chart below shows how Lopezlopez 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 Lopezlopez surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
