Origin
Meaning and origin of Dumandan
The surname Dumandan is believed to have originated in the Philippines during the Spanish colonial period. It is thought to be derived from the Spanish words "de la mano," which translate to "of the hand." This could indicate that the name was initially given to someone who worked with their hands, such as a craftsman or a laborer.
One of the earliest recorded instances of the name Dumandan can be found in the records of the town of Taal in the province of Batangas, dating back to the late 18th century. It is possible that the name was initially brought to the region by Spanish settlers or missionaries.
In the early 19th century, a man named Juan Dumandan was recorded as a landowner in the town of Lipa, also in the province of Batangas. This suggests that the family had achieved a certain level of prosperity and social standing by that time.
Another notable bearer of the name was Francisco Dumandan, who was born in the town of Bauan in Batangas in 1832. He was a prominent figure in the Philippine Revolution against Spanish colonial rule, serving as a captain in the revolutionary forces.
During the American colonial period in the early 20th century, a man named Teodoro Dumandan was a prominent educator and administrator in the Philippine public school system. He worked tirelessly to improve educational opportunities for Filipino children.
In more recent times, the name Dumandan has been carried by several notable individuals in various fields. Rodolfo Dumandan, born in 1938, was a renowned Filipino artist and sculptor whose works were exhibited internationally. Meanwhile, Renato Dumandan, born in 1947, was a respected journalist and author who wrote extensively on Philippine history and culture.
While the Dumandan name is most commonly found in the Philippines, there are also small communities of individuals with this surname in other parts of the world, likely descendants of Filipino emigrants.

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