Čulina

Čulina is a surname predominantly found in Croatia. It is derived from a hypocoristic (diminutive) form of a given name. The most probable origin is from the masculine given name "Nikola" (Nicholas), or potentially from other names ending in "-ko" or "-lo", with the diminutive form evolving into "Čulo" and subsequently "Čulina" as a patronymic surname denoting "belonging to Čulo" or "descendant of Čulo."

The surname is relatively common in the Dalmatian region of Croatia, particularly in the areas surrounding Split and Šibenik. While the exact historical records of the surname's first appearance are not readily available in comprehensive genealogical databases, its prevalence suggests origins within the broader Slavic naming traditions of the region.

The surname may have variations or related forms depending on dialectical differences or historical migration patterns. Further research into specific family lineages bearing the name would be required to determine more precise origins for individual families.
