Kizzie is a name of unknown origin, believed to have been created for literary use during the late Victorian era. It was popularized through George du Maurier's novel 'Trilby' (1894), in which Kizzie is a character who is said to be 'the prettiest girl at the school'. This usage likely contributed to its brief appearance as a given name around that time.
The name Kizzie had a varied popularity over time, with a significant peak in the late 1970s (286 births in 1977). After that, its usage sharply declined and has remained low since the early 1980s.
