Origin
Meaning and origin of Santimaw
The surname SANTIMAW has its origins in the Iberian Peninsula, tracing back to the medieval period. It is believed to have emerged in the northern regions of Spain, particularly in the Basque Country and Navarre, where it was likely derived from a combination of the Spanish words "santa" and "maw," meaning "holy" and "mother," respectively.
One of the earliest recorded instances of the surname SANTIMAW can be found in the medieval Catalan manuscript "Llibre dels Fets," which chronicles the life and conquests of King Jaume I of Aragon (1208-1276). This document mentions a certain Ferran SANTIMAW, who served as a notable knight and advisor to the king during his campaigns in the Balearic Islands.
In the 14th century, the SANTIMAW family appears to have established a presence in the town of Pamplona, Navarre. Local records from this period, such as the "Registro de Hidalguía de Navarra," include entries for several individuals bearing this surname, indicating their noble status and land ownership in the region.
During the 15th and 16th centuries, the SANTIMAW name gained prominence in various parts of Spain, with several notable figures emerging. One such individual was Alonso SANTIMAW (1472-1539), a renowned scholar and theologian who served as the Archbishop of Seville and played a crucial role in the Spanish Inquisition.
Another prominent figure bearing the SANTIMAW surname was María SANTIMAW (1555-1628), a celebrated poet and playwright from Granada. Her works, which included religious plays and sonnets, were widely acclaimed during her lifetime and contributed to the flourishing of Spanish literature in the Golden Age.
In the 17th century, the SANTIMAW name found its way to the New World, as Spanish explorers and settlers ventured across the Atlantic. Juan SANTIMAW (1602-1678), a navigator and cartographer, accompanied several expeditions to the Caribbean and Central America, contributing to the mapping of new territories and the establishment of Spanish colonies.
As the centuries progressed, the SANTIMAW surname spread across various regions of Spain and its overseas territories, adapting to local dialects and spellings. In the 19th century, notable figures included Ignacio SANTIMAW (1832-1912), a prominent Mexican politician and statesman who served as the Minister of Foreign Affairs during the presidency of Porfirio Díaz.
Throughout its long and illustrious history, the SANTIMAW surname has been carried by individuals from diverse backgrounds, ranging from nobles and clergy to artists, explorers, and political leaders, leaving an indelible mark on the cultural and historical tapestry of the Iberian world.

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 Santimaw surname at the time of the 2020 Census, not any inherent property of the name itself.
