Jackaline is of French origin, derived from the male name Jacques, which means 'supplanter' or 'he who supplants'. It gained popularity in the late 20th century, likely due to its unique sound and association with common English names like Jacqueline and Jackeline.
"The name Jackaline experienced its peak popularity between the years 1934 and 1942, with six births occurring each of those four years. After a dip in the following decades, it saw a resurgence in the late 1960s to early 1980s, with five births recorded during these periods. In total, there were thirty-nine babies named Jackaline born between 1934 and 1982."
