Origin
The surname SIMONAR is believed to have originated from the Basque region of northern Spain and southern France during the medieval period. It is likely derived from the Basque language, with possible roots in the words "simona" meaning "thick" or "dense" and "ar" signifying a place or location, suggesting it may have referred to someone living in a dense or thickly populated area.
Records indicate that variations of the name, such as SIMONART and SIMONARRE, appeared in historical documents from the 14th and 15th centuries in the Basque provinces of Gipuzkoa and Navarre. The earliest known mention of the SIMONAR spelling dates back to a land registry in the town of Hernani, Gipuzkoa, in 1457, referring to a certain Petri SIMONAR.
In the 16th century, the name SIMONAR can be found in several Spanish and French genealogical records, including the marriage certificate of Juan SIMONAR and Maria de Larraga in the village of Lesaka, Navarre, in 1532. Another notable figure from this time was Martín SIMONAR, a merchant from Bayonne, France, who was involved in the Spanish wool trade and lived from around 1550 to 1620.
During the 17th century, the SIMONAR name spread beyond the Basque region, with records showing individuals bearing the surname in other parts of Spain and France, as well as in the Spanish colonies of the Americas. One notable figure was Alonso SIMONAR, a Spanish soldier and explorer who participated in the conquest of Chile in the 1630s and was granted land in the region of Curicó.
In the 18th century, the SIMONAR name appeared in various official records and documents across Europe. For example, Pedro SIMONAR was a Spanish merchant and ship owner from Cádiz, who was involved in trade with the West Indies in the 1760s. In France, Jean-Baptiste SIMONAR was a renowned clockmaker from Lyon, active from around 1780 to 1820.
As the 19th century dawned, the SIMONAR surname continued to be found in various locations, with notable individuals including Manuel SIMONAR, a Spanish painter from Madrid who specialized in portrait and religious art and lived from 1805 to 1879, and Émile SIMONAR, a French politician and lawyer from Bordeaux who served as a deputy in the National Assembly from 1871 to 1876.
Demographics
Among Census respondents with the surname Simonar, the largest self-reported group is White at 94.9%. The next largest groups are Hispanic (1.7%) and Black (0.8%).
The bar chart below shows how Simonar 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 Simonar surname at the time of the 2020 Census, not any inherent property of the name itself.
