Romo
A surname that likely began as a nickname for someone with a blunt, shortened, or “stumpy” feature, from a Spanish word meaning “blunt” or “dull.”
The #1,343 most common surname in the United States (2010 Census) — about 1 in every 11,747 Americans shares it.
Etymology
Spanish romo means “blunt,” “dull,” or “not pointed,” and by extension could describe a person, edge, nose, or other feature that was rounded off or stunted. The word is commonly traced back to Latin rōm(u)s or related forms used for something blunt or truncated. As a surname, it would most naturally have started as a descriptive nickname for a person with such a characteristic.
History
The excerpts show Romo listed among Spanish surnames formed from physical traits or personal qualities, alongside names like Calvo and Zazo. This fits a common medieval naming pattern in which descriptive bynames later became hereditary surnames. The name remains well established in the Spanish-speaking world and is especially familiar in Hispanic America.

Fun fact
In older Spanish usage, romo could describe a sword, tool, or other object with a blunted tip, not just a person.
