Kiou Surname Meaning
The Greek surname Kiou (Κιού) is the genitive form of Kios (Κίος), with the ending -ou (-ού) indicating “of Kios” or “belonging to Kios.” The name Kios may refer to the ancient city of Cius (Κίος) in Asia Minor, suggesting a geographic origin. In Greek surname formation, place-based identifiers frequently became hereditary surnames when individuals were identified by their origin. Through ecclesiastical and administrative records, genitive constructions such as Kiou stabilized into family names. The surname Kiou therefore means “descendant of the one from Kios,” preserving paternal lineage rooted in geographic origin.
