Jaclin is of French origin, derived from the masculine name Jacqueline, which was derived from the given name Jacquette, a diminutive of Jacquette, meaning 'littlejacquemin', a type of flower. It has been used sparingly as a feminine name in France and other Francophone countries.
The name Jaclin appears to have been moderately popular between the late 70s and mid-90s, with peaks in 1976 (8 births), 1986 (13 births), and 1994 (10 births). However, it seems to have lost popularity afterwards, with fewer than 10 births per year from 1995 onwards. Overall, there were a total of 153 Jaclins born over this period.
