Origin
Meaning and origin of Sajuan
The surname SAJUAN is believed to have originated in Spain, with its roots dating back to the 15th century. The name is thought to be derived from the Spanish town of San Juan, which translates to "Saint John" in English. This town is located in the province of Alicante, in the Valencian Community of eastern Spain.
One of the earliest recorded instances of the SAJUAN name can be found in a manuscript from the year 1492, which documented the inhabitants of the town of San Juan. This manuscript listed several families with the surname SAJUAN, suggesting that the name had already been established in the region by that time.
During the 16th century, the SAJUAN name began to spread beyond the town of San Juan, as families migrated to other parts of Spain and even to the Spanish colonies in the Americas. One notable individual bearing this surname was Diego SAJUAN, a Spanish explorer who accompanied Hernán Cortés on his expeditions to Mexico in the early 1500s.
In the 17th century, the SAJUAN name appeared in various historical records from different regions of Spain. For instance, a document from 1642 mentioned a Juan SAJUAN, a wealthy landowner in the city of Seville. Additionally, a church record from 1671 in the town of Zaragoza listed the marriage of Isabel SAJUAN and Pedro Martínez.
As the SAJUAN family continued to expand and disperse throughout Spain and its colonies, some variations in the spelling of the name emerged. These included SAJUÁN, SANJUAN, and SAN JUAN, among others. However, the core of the name remained consistent, reflecting its connection to the town of San Juan.
During the 18th and 19th centuries, several notable individuals bore the SAJUAN surname. One example is María SAJUAN, a renowned Spanish painter who lived from 1778 to 1853 and was celebrated for her portraits and religious works. Another significant figure was Antonio SAJUAN, a Spanish military officer who fought in the Napoleonic Wars and later served as a governor in Puerto Rico, where he was born in 1792.
Throughout its history, the SAJUAN surname has been carried by numerous individuals across various professions and walks of life. From explorers and artists to landowners and military leaders, the name has left its mark on the cultural and historical tapestry of Spain and its former colonies.

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.
