Medieval
diminutive of
Æðelþryð. This was the name of a 7th-century
saint, a princess of East Anglia who founded a monastery at Ely. It was also used by William Shakespeare for a character in his comedy
As You Like It (1599). At the end of the Middle Ages the name became rare due to association with the word
tawdry (which was derived from
St. Audrey, the name of a fair where cheap lace was sold), but it was revived in the 19th century. A famous bearer was British actress Audrey Hepburn (1929-1993).
