Earldene is an uncommon, yet distinctive given name of American origin. It's composed of two elements: 'earl,' which is of Old English derivation and denotes a nobleman or ruler, and '-dene,' a suffix of Anglo-Saxon roots that signifies valley. Thus, Earldene could be interpreted as 'valley of the nobles' or 'noble valley.' The name first gained notable usage in the United States during the mid-20th century but has since remained quite rare.
There were no recorded births of the name Earldene in any year besides 1925, when there were exactly five instances of this name being given to newborns.
