Jolleen is of American origin, a variant spelling of the feminine given name Julie. It means 'youthful' or 'downy young one,' derived from the French 'Jeune.' The name Jolleen gained some popularity in the United States during the late 20th century but remains relatively uncommon today.
The name Jolleen has seen fluctuations in popularity over the years, with a notable spike in the late 1970s and early 1980s. The peak occurred in 1975 with ten births, followed by nine births the next year. However, since then, its usage has significantly declined, with only five or fewer births per year from 1986 onwards, including two recent years with a single birth each (2010).
