Sharline is of French origin, derived from the name Chardonnay, which was originally a variety of white grape used to make wine. The name Sharline is thought to have been coined in the 1970s and gained popularity in the United States during the decade. It is composed of ' Шар', meaning 'clear' or 'bright' in Russian, and '-line', suggesting a connection to the musical term 'melody'. However, there's no definitive link between Sharline and music. The name is often associated with elegance and sophistication, likely due to its French roots and the fact that it shares its ending with many popular names of the era.
"Sharline appears to have been a popular name from the late 1930s to the mid-1960s, with peaks of 12 births per year in 1957 and 1958. However, it fell out of favor thereafter, with only 6 or fewer births recorded each year since 1987."
