The Ultimate Harry Potter Names

These are all the names that are in the books, well "usable" names because I think we can all agree that the name Dobby, Griphook, and Buckbeak are unusable for children.

Once a poetic Celtic name, that of the angel who governs the month of June, Muriel has for a time, become the mom or grandma of TV sitcoms. A Top 200 name from 1912 to 1933, Muriel might just be due for a comeback, fitting as it does with the likes of Margot, Mabel, Marjorie, and Marilyn. 
 
Traditionally written as Muirgel in Old Irish, it was also common in Medieval England (often in the form of Merial) and while it did see a decline after the Norman Conquest, it didn't disappear completely. The Muriel form remained familiar in Scotland and was eventually brought back to England in the 1850s, following its appearance in Dinah Craik's novel, John Halifax, Gentleman.

Muriel has further literary cred via Edinburgh-born author Muriel Spark, author of The Prime of Miss Jean Brodie and also appears as a character in l. M. Montgomery's Anne of Green Gables, in George Orwell's Animal Farm, and in Anne Tyler's The Accidental Tourist.
 
Ultimately derived from the Old Irish elements muir and gel, Muriel is an water-inspired choice meaning "sea bright" or "bright sea". Distinctive in sound (MYURE-ee-uhl in English; MUE-RHYEL in French), Muriel was given to 50 girls in the US in a recent count: the highest number recorded since the 80s!

Muriel

Long in our category of so-far-out-it-will-always-be-out category, once seen as a gum-cracking 1940's telephone operator, we think it's time to reassess Myrtle, and look at is as a nature name, a plant with pink or white aromatic berries. Ruled by Venus, myrtle is a plant associated with love, peace, fertility and youth.
 Myrtle has lots of literary references as well: in Thomas Hardy's The Hand of Ethelberta, Theodore Dreiser's The Genius, P. G. Wodehouse's Meet Mr Mulliner, and especially The Great Gatsby. Fitzgerald's Myrtle Wilson has been played on film by actresses as varies as Shelley Winters, Karen Black and Isla Fisher.
