Francisco
A surname ultimately from the Latin name Franciscus, meaning “Frenchman” or “free man,” and often used in honor of St. Francis.
The #1,481 most common surname in the United States (2010 Census) — about 1 in every 12,814 Americans shares it.
Etymology
Francisco comes from the personal name Franciscus, the Latin form of Francis. That name was originally associated with the Franks and could mean “Frenchman,” though in medieval Christian usage it was strongly linked to the idea of freedom and to St. Francis of Assisi. As a surname, Francisco usually developed from an ancestor’s given name rather than from a place or occupation.
History
The surname is especially common in the Iberian world and in communities shaped by Spanish and Portuguese naming traditions. It also appears in the wider European diaspora and in the Americas through migration and colonial-era naming patterns. The historical excerpts include only incidental mentions, not a direct dictionary etymology, so the explanation here follows standard onomastic usage for the name.

Fun fact
Because Francisco was also a very popular baptismal name, many surnames of this form arose independently in different families rather than from one single ancestral line.
