Alexiou is a Greek surname formed from the personal name Alexios. It belongs to the broad Greek patronymic tradition in which a baptismal name became a hereditary family surname over time.
Meaning and Origin
The surname is usually understood as meaning of Alexios or belonging to the Alexios line. The personal name Alexios is related to Greek name elements associated with helping or defending, but the surname itself is best read as a patronymic family identifier.
Earliest Known Regions and Historical Context

Migration and Diaspora Patterns
Alexiou often remains recognizable in Latin-alphabet records, though some families may appear under simplified spellings or related forms based on Alexis or Alexios. Passenger lists, naturalization files, and parish records are useful for connecting diaspora branches to local Greek origins.

Research Notes
Because the surname comes from a personal name rather than one unique place, the strongest evidence usually comes from a precise locality, Greek-script spelling, and associated family clusters.
Common Misconceptions
