History & Origin

Cullin is a variant spelling of the Irish surname Cullen used as a first name. It appears in United States records from about 1917 but, unlike most names of this cohort, reached its small high around the year 2000, riding the modern taste for Irish surname names. It stayed rare in this spelling, given to only a couple dozen boys a year even at its peak.

That late peak makes Cullin unusual among early-century rarities: it reads less as a vintage name than as a modern surname-style choice alongside Colin and Cullen. The standard Cullen is far more common; Cullin remains a minority spelling for parents who prefer the look of the double-l form.

Did you know? Cullen, and so Cullin, may mean 'holly' - the evergreen - or 'young hound,' depending on which Irish family the surname came from.
