Agustín
A surname from the personal name Agustín, ultimately tied to Saint Augustine and the Latin name Augustinus.
The #5,458 most common surname in the United States (2010 Census) — about 1 in every 48,431 Americans shares it.
Etymology
Agustín is a surname formed from the given name Agustín, the Spanish form of Augustine. That personal name comes from Latin Augustinus, meaning “belonging to Augustus” or “of Augustus,” the imperial title/name. In practice, the surname usually began as an identification with someone named Agustín rather than as a separate lexical word.
History
The excerpts point to Agustín as a Spanish name linked to Saint Augustine, and one source notes variant spellings such as Agostí and Agustí. As with many surnames derived from a baptismal name, it would have developed independently in different families and regions. The form is especially associated with Spanish-speaking areas, and the accent mark is often dropped in anglicized contexts or in records.
