Meaning & origin
Aletha is a feminine name that saw its greatest popularity in the early 20th century, peaking in 1923 (the peak year from the Social Security data). It first appeared in U.S. records in 1881, nearly a century after the nation's founding, suggesting it was a rare choice even then. The name has been falling out of use since around 1985, with no births recorded in the most recent years. Its top-ranked year was only 951st, meaning it never broke into mainstream popularity. Aletha's similarity to the more common Althea may have contributed to its obscurity, but it retains a classic feel with its Greek roots. The name has no strong regional concentration in the U.S., as it never appeared among top states. Parents considering Aletha today are likely drawn to its vintage charm and understated elegance.
Aletha is a variant of Althea, which is derived from the Greek name Althaia, possibly from althos meaning 'healing' or aletheia meaning 'truth'. The name has been used in England since the 17th century, likely influenced by the mythological Althaea, mother of Meleager. In modern times, Aletha is a less common spelling, with occasional use in the United States from the late 19th century.
