Andreo

Andreo is a surname and, less commonly, a given name used in some Spanish- and Italian-speaking communities. As a surname, it is typically treated as patronymic, derived from a presumed ancestor named Andreo, Andreu, or a variant of the given name Andrew.

The name Andreo traces its roots to the given name Andreo (a variant of Andrea in Italian or Andreas in Greek), which in turn derives from the Greek Andreas, meaning manly or masculine. In Iberian and Italian naming traditions, diminutive or affectionate forms often become family names over time.

Geographically, Andreo appears in documents in Spain and Italy and in diaspora communities around the world. It is commonly found in Latin American countries as a result of historical migration and settlement. In modern usage, Andreo is primarily a surname; given-name usage is rare and regional.

Variants and related forms include Andreu (Catalan), Andre (French and Portuguese contexts), Andres or Andréas in some Hispanic contexts, and other phonetic spellings that arose from transliteration. The spelling Andreo may also appear in historical records with regional orthographic variations.

Notable individuals with the surname are documented in historical registries and public records across regions where the name is present, though the spelling can vary by country.
