Artemis815's list "Vintage girls" of 3 great name ideas: Dinah - Imogen!

Vintage girls

Dinah is a charming, underused Old Testament name with a rich literary and musical resume. In the Old Testament, Dinah was the beautiful daughter of Jacob and Leah and while some conflate her with the Biblical Adinah, they are in fact different figures.
 Meaning "God will judge", Dinah is the heroine of the best-selling Anita Diamant novel The Red Tent, and is also a central character in the George Eliot novel Adam Bede, where she acts as a moral center. In the classic film The Philadelphia Story, Dinah is the heroine's sassy kid sister while it also appears in Alice in Wonderland as the name of Alice's kitten. 
 One important thing to note is that "Aunt Dinah" has been used as a racial stereotype, from the character of the cook in Harriet Beecher Stowe's Uncle Tom's Cabin. It may also sound too reminiscent of the American diner in some accents. 
 The name Dinah was adopted by two great singers: Dinah Washington (born Ruth) and Dinah Shore (born Frances).

This Celtic goddess and Arthurian name may sound terminally old-ladyish to many ears--but so did names like Ella and Etta not so long ago. So Enid is yet another forgotten four-letter E-possibility: she's has been M.I.A since 1954. 
 You might not know it to look at her, but Enid is Welsh, from the word meaning 'life' or 'soul.' Back in the Age of Chivalry, to call a woman 'a second Enid' was the greatest of compliments, as she was a legendary romantic figure, revived in Tennyson's Idyll of the Kings. In more modern times, Enid is the title of a Bare Naked Ladies song and a quirky character in the quirky film Ghost World.

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.
 
Though never in the American Top 1000, Imogen may be more popular in your hip neighborhood than that statistic would suggest. A contemporary classic in England and Wales, Imogen has ranked in the Top 100 ever since detailed naming records began in 1996. It's also a Nameberry favorite, consistently among the Top 100 most viewed girl names on our site.
 
The story goes that Imogen originated as a Shakespearean printer's misspelling of the traditional Celtic name Innogen, used by him for a character in one of his last plays, Cymbeline. The Innogen of legend, who Shakespeare’s character was based on, was the wife of Brutus of Troy, the first king of Britain. Earlier versions of her name, including Ennoguent, Innoguend, and Innoguent, were found in Brittany from the 9th-11th centuries. They are probably derived from the Gaelic word inghean, meaning "daughter" or "maiden," and possibly have a connection to the Proto-Celtic word for "white," from which the suffixes -gwyn and -gwen evolved.
 
Even if Shakespeare did happen upon Imogen by accident, he wasn't the first person to use the name. The Latin name Imogenis, meaning "lowest-born," existed centuries before Shakespeare, and was first recorded in the 13th century.
 Imogen gained attention in recent times through its link to Grammy-winning musician Imogen Heap. Other pluses: Imogen has the wonderful namesake photographer Imogen Cunningham and also a meaning that can't be topped. Immy is the cute diminutive; in the book and movie Fried Green Tomatoes, the character Imogene's nickname was Idgie.
