Delaney

Derived from the Irish surname Ó Dubhshláine, rooted in elements translating roughly to dark defiance. It circulated in America strictly as a family name for generations before crossing over into the first-name registry during the late twentieth century. By the time it gained national momentum, it settled almost entirely into the girls' column.

A Delaney is overwhelmingly likely to have been born in the twenty-first century. The name reads as upbeat, organized, and comfortable on a sports roster or a syllabus. With an estimated average age of eighteen, it carries no midcentury dust and almost no memory of the dial-up internet era. It tends to move through childhood without being shortened.
