Etheldreda, derived from Old English elements 'æthel' meaning noble and 'þryð' signifying strength, was a popular name among Anglo-Saxons during the early medieval period. The name fell out of use after the Norman Conquest but was revived in the 19th century, with notable bearers including Etheldreda Balch (1856-1927), an American painter known for her portraits and landscapes.
"Etheldreda was quite popular in 1916 with five babies bearing the name that year."
