Ælfthryth combines the Old English ælf (elf) and thryth (strength). **Queen of England (c. 945-1000)** — wife of King Edgar the Peaceable, mother of Æthelred the Unready. **The first English king's wife to be formally consecrated as queen** (Bath, 973). **Notoriously accused of arranging the murder of her stepson Edward the Martyr** at Corfe Castle in 978, clearing the way for her own son's accession.
Featured in Anglo-Saxon Chronicle and later hagiographies.
Ælfthryth reduces to eight — the number of consecrated queen.
