As others have said, very few names are of 'Old English' (ie Anglo-Saxon) origin. Like the English language itself, 'English' names are a blend of Anglo-Saxon plus a bit of Norse and celtic with Biblical/Christian influences and French/Latin imports. Foreign marriages of medieval/early royalty introduced new names; so did the arrival of the Hanoverian dynasty. Since the 1800s, if not before, there has been increasing use of names from Wales, Ireland, Scotland and many, many other countries.
The following have been used in England since the 1600s, some before:
Maud
Dorothy
Judith
Julian/Gillian
Hester
Blythe
Mariota (various spellings)
Hawise (medieval, really)
Deborah
Frances
Susan
Lettice (Laetitia)
Ann, Anna
Marian/Marion (Robin Hood!)
Mary
Bridget
Blanche
Katherine
Eleanor, Beatrice (mostly royalty)
Adeliza (= daughter of William the Conqueror - tho' he was Norman, of course. He also had daughters called Constance and Adela.)
Celia, Phyllis, Diana and other classical 'nymph'/goddess names were introduced by Renaissance poets; so was Stella, but none were widely used.
If, however, you want just Anglo-Saxon names, then these have survived,in modern form:
Elfrida
Ethel
Edith
Edwina
Godiva
Hilda
Mildred
Sunniva
Winifred
