Ethel (also æthel) is an Old English word meaning "noble", today often used as a feminine given name.
[1][2] It is frequently attested as the first element in Anglo-Saxon names, both masculine and feminine, e.g. Æthelhard, Æthelred, Æthelwulf; Æthelburg, Æthelflæd, Æthelthryth (Audrey).
It corresponds to the Adel- and Edel- in continental names, such as Adolf (Æthelwulf), Albert (Adalbert), Adelheid (Adelaide), Edeltraut and Edelgard.
Some of the feminine Anglo-Saxon names in Æthel- survived into the modern period (e.g. Etheldred Benett 1776–1845).
[4] Ethel was also occasionally used as a masculine given name during the 1880s to 1910s, but never with any frequency (never rising above rank 400, or 0.02% in popularity).
