Letha

Letha is a name with Greek roots, derived from 'Lethe,' one of the five rivers of the underworld in Greek mythology. Drinking from the river Lethe caused souls to forget their earthly lives before reincarnation. While the mythological association is ancient, the name Letha itself gained some popularity in the United States, particularly in the late 19th and early 20th centuries. It is often considered a variant or short form of names like Letitia, though its direct connection to the Greek mythological river is also recognized.

The name's usage in America might have been influenced by a general trend of adopting classical names during certain periods, or it could have emerged as a unique-sounding alternative to more common names. Despite its somewhat somber mythological meaning, Letha has been used as a given name without necessarily carrying negative connotations for its bearers. Its peak popularity has passed, making it a less common choice today.
