The name Jacklin is of English origin, derived from the surname Jacqueline, which itself stems from the French feminine given name Jacqueline. The latter is a compound of the French elements 'Jacques' meaning 'supplanter', and '-eline', a feminine suffix. Thus, Jacklin can be interpreted as a diminutive or familiar form of Jacqueline. Historically, this name has been more prevalent in English-speaking countries but has gained popularity worldwide over time.
"The name Jacklin was quite popular from the mid-40s to the late-50s, with a peak of 23 births in 1956. After that, it fluctuated but remained moderately common until the late 70s, when it started to decline. There's been a slight resurgence since the year 2000, but overall, its popularity has decreased significantly over time."
