Guerra
A surname from the word for “war,” often first used as a nickname or byname for a warrior or someone linked to conflict.
The #473 most common surname in the United States (2010 Census) — about 1 in every 4,406 Americans shares it.
Etymology
Guerra comes from the Romance word for “war,” inherited from Latin war-related vocabulary and used in medieval Iberian and Italian naming. As a surname, it most likely began as a descriptive byname for someone associated with fighting, military service, or a warlike temperament. In some cases it may also have been applied in a broader social or symbolic sense, since medieval surnames often arose from vivid personal labels.
History
The surname is especially common in Spain, Italy, and the Portuguese-speaking world, and it spread widely to the Americas through migration. It appears in historical surname lists and discussions as a Romance-language name connected with warlike or martial associations. Because the word itself is very common, the surname may have arisen independently in more than one place.

Fun fact
Because Guerra is also the ordinary word for “war” in several Romance languages, it can look like a dramatic nickname surname even when it simply reflects a medieval byname.
