The name Harleth is a girl's name of English origin. Harleth and discussed in our forums with posts like "Picky Parents BNG".
From the experts:
Harleth is a name which probably stems from combining the oh-so-trendy Harlow with the evergreen Elizabeth. However, literary parents may also remember the beautiful but difficult character Gwendolen Harleth from George Eliot's Daniel Deronda. Harleth has a fashionable edge to it, being associated with rising supermodel Harleth Kuusik. We think that Harleth is a pretty alternative to Harlow and hope to see more of it.
