Elfrida is a female given name, the variant of Elfreda. Both names are modern revivals of the Old English name Ælfþryð, which is composed of the elements ælf "elf" and þryþ "strength", giving it the meaning "elf strength". This name was common among Anglo-Saxon nobility and appears in various medieval forms including Ælfthryth. Despite its old roots, the name fell out of use after the Norman Conquest and was only revived in the 19th century in both England and Germany. History and Notable Bearers The name Elfrida, along with its variants such as Elfrieda and Elfriede, gained popularity in the 19th century as part of a broader revival of medieval names. In medieval times, several notable Anglo-Saxon women bore variations of the name, including Ælfthryth, Countess of Flanders (daughter of King Alfred the Great), and Saint Ælfthryth of Crowland. The name also appears as Elftrude in some historical records. Notably, Ælfþryð was the name of the mother of King Æðelræd the Unready. Related Forms and Cultural Use Besides Elfrida, the name has several other forms across languages and cultures. The Anglo-Saxon original Ælfþryð is the earliest form. In German, it developed into Elfriede, with diminutives like Elfi, Frieda, and Friede. It is sometimes confused with Alfred, which derives from Ælfræd meaning "elf-counsel" or "wise-elf". Elfrida remains in occasional use today, particularly in English-speaking countries and Germany.
