Sosa
A surname most often tied to the Spanish form of Souza/Sousa, originally a place-name meaning a marshy or willow-lined spot.
The #650 most common surname in the United States (2010 Census) — about 1 in every 5,886 Americans shares it.
Etymology
Sosa is commonly treated as a Spanish spelling or adaptation of Portuguese Souza/Sousa. Those forms go back to a Latin place-name element often linked with a marsh, damp ground, or a willow tree, so the surname likely began as a locational name for someone from such a place. In older scholarship, it is sometimes grouped with surnames derived from Portuguese Souza.
History
The name is found in Spanish- and Portuguese-speaking regions and later spread widely through migration to the Americas. In modern usage it can appear as both a surname of Iberian origin and, in some families, a variant influenced by spelling changes across languages. The form is especially common in Latin America and among people with Iberian or Hispanic ancestry.
