Jaclyn is of Irish origin and means "supplanter" or "god will protect". It's a modern variant of the traditional Irish name Jacqueline, which was formed from the French name Jacquette, a pet form of Jacques. Jaclyn first gained popularity in the United States during the mid-20th century. It reached its peak usage in the 1970s and has since remained a steady choice for parents. The name Jaclyn is often associated with warmth, charm, and sophistication. Its spelling variation, Jacqueline, is also widely recognized due to famous figures like Jacqueline Kennedy Onassis. In recent years, there has been an increasing trend towards shorter forms of names, contributing to Jaclyn's continued popularity alongside its shortened versions such as Jackie and Jax.
