Locket

The word 'locket' itself emerged in the English language in the 17th century, derived from the Old French 'loquet' meaning 'a latch' or 'a small lock'. It referred to a small case or pendant, typically worn around the neck, designed to hold a miniature portrait, a lock of hair, or other small memento. As a given name, 'Locket' is exceedingly rare and appears to be a modern adoption of the word, likely chosen for its delicate, sentimental, and somewhat whimsical connotations, rather than having a long history as a traditional personal name.
