The name Caley is believed to have originated from the Gaelic language, which is a Celtic language spoken primarily in Scotland and Ireland. It is thought to be derived from the Gaelic word "cailleach," which means "old woman" or "nun."

In ancient Celtic mythology, the Cailleach was a powerful female figure associated with winter, storms, and the natural world. She was often depicted as an old woman or a hag, but was also revered as a wise and powerful goddess. The name Caley may have been used to honor this mythological figure or to invoke her protection.

One of the earliest recorded uses of the name Caley can be found in the 16th century Scottish text, "The Complaynt of Scotland," written in 1549. This literary work mentions a character named "Caley," though it is unclear whether this was a given name or a surname.
