Bonniejean is an uncommon yet charming given name of American origin, derived from combining the elements 'bonnie', meaning 'pretty' or 'beautiful' in Scottish Gaelic, and 'Jean', a French form of 'Jane'. This compound name gained popularity during the mid-20th century but has since become quite rare. It is often shortened to Bonnie for everyday use.
"Bonniejean experienced its peak popularity in the late 1960s to early 1970s with a total of 32 births recorded between 1962 and 1973."
