Ethelred

Ethelred is an Old English name derived from the elements 'æthel' meaning 'noble' and 'ræd' meaning 'counsel' or 'advice'. It was a royal name in Anglo-Saxon England, most famously borne by King Æthelred the Unready. The name fell out of common use after the Norman Conquest but saw a brief revival in the 19th century due to interest in Anglo-Saxon history.

Despite its royal pedigree, the name's association with 'the Unready' (a mistranslation of 'unræd', meaning 'ill-advised' or 'poorly counseled') likely contributed to its decline in popularity. It is now considered a rare and historical name, primarily known through its historical context.
