Agosto
A surname likely taken from the month name or feast day of August, ultimately from Latin for “the revered one.”
The #6,103 most common surname in the United States (2010 Census) — about 1 in every 54,947 Americans shares it.
Etymology
Agosto is the Spanish and Italian word for the month of August, from Latin Augustus. In Latin, Augustus was originally an honorific meaning “venerable” or “consecrated,” later associated with the Roman emperor Augustus and then with the month named after him. As a surname, Agosto was probably used for someone born in August, connected with a feast day in that month, or otherwise identified by the month-name as a nickname.
History
The name is found in Spanish- and Italian-speaking areas as both a place and month name, so the surname likely arose independently in more than one region. In modern records it is especially common in Hispanic communities, including the United States and the Caribbean. Because the supplied excerpts only mention August as a month/date, they do not establish a family-specific origin for the surname itself.
