Jeanita is of American origin, derived from the French 'Jeannette', which is a diminutive of 'Jeanne'. It was originally given as a pet form of Jane, but over time, it has evolved into a name in its own right. The name Jeanita gained popularity in the United States during the mid-20th century and continues to be used today.
The name Jeanita experienced varied popularity over the years, with peak periods from 1944 to 1948 and again from 1960 to 1963, where it consistently ranked among the top choices for newborn girls. However, its usage has significantly declined since the late 1970s, as indicated by the total of 281 births recorded over this period.
