Aletha

Alethea is an English language female first name derived from the ancient and modern Greek feminine noun αλήθεια (pronounced "al-ee-thia"), meaning "truth". It is thus an equivalent of the name Verity, from the Latin feminine noun veritas, "truth". As an English first name it is frequently pronounced in modern times in an Anglicised form as "Ala-thee-a". The name dates from the 16th century, as given in 1585 to Alethea Talbot (1585–1654), the youngest daughter of Gilbert Talbot, 7th Earl of Shrewsbury and later Countess of Arundel following her marriage to Thomas Howard, 21st Earl of Arundel. The name as used for the daughter of a wealthy nobleman in the Renaissance era in England would certainly have been pronounced "Al-ee-thia", that is as an Ancient Greek word, as the father would have received a thorough education in Ancient Greek and Latin and would thus be aware of the correct pronunciation. Women named Alethea include:
Alethea Charlton (1931–1976), British actress
Alethea Garstin (1894–1978), English painter and Royal Academician
Alethea Hayter OBE (1911–2006), English author and British Council Representative
