Earl Talbot: Earl Talbot is a title that has been created twice in the Peerage of Great Britain.  This branch of the Talbot family descends from the Hon. Sir Gilbert Talbot (died 1518), third son of John Talbot, 2nd Earl of Shrewsbury.  His great-great-great-grandson the Right Reverend William Talbot was Bishop of Oxford, of Salisbury and of Durham.  His eldest son Charles Talbot was a prominent lawyer and politician.  In 1733 he was raised to the Peerage of Great Britain as Lord Talbot, Baron of Hensol, in the County of Glamorgan, and then served as Lord Chancellor of Great Britain from 1733 to 1737.

Alethea: 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:
