I got it! Deseret.
Claret? (Better than Brandy or Rose)
The coolest girl’s name I saw last school year was Saber. If I were going to use it as a name, I would make it Sabre.
We have an office assistant named Jordyn.
Irulan
Alia
Both from DUNE.
So… you have SEVEN CHILDREN and are thinking about having ANOTHER ONE???
Jumping Jesus on a Pogo Stick!
(It’s amazing how standards have changed in the past 100 years or so, particularly in 1st world nations… two children is now average, three is a lot, four is a HUGE number, and anything more than four is cause for pointing and whispering…)
Good on you for adopting, though. And, if you want a name that is both literary and a reference to child #8, you can’t go wrong with Octopussy. Or if you don’t have the balls for that, Octavia.

Just for fun, Shakespeare names I like:
Imogen (Cymbeline)
Adrian (The Tempest)
Ophelia (Hamlet)
Aliena (As You Like It)
Viola (Twelfth Night)
Francesca (Measure For Measure)
I particularly like Imogen and Aliena.
“Aphra,” after Aphra Behn, writer and spy.
And it’s close to “Alpha.” Which is why it’s always the first name to come to mind. Fnord.
As a side note, the difference between 6 and 7 (when talking with other folks) is the difference between:
(6) You guys really must like kids.
(7) Are you out of your mind?
I can’t wait to hear what people say about 8. 
Here is a picture of the three (Jett, Scout, Scarlett), just in case anyone needs a visual.

Phaedra?
Yola, after Chris Isaak’s manager on Showtime
Henrietta and you could call her Henri for short.
What a darling group you’ve got there:)
Great picture!
They almost look like a three headed monster. 
What are the other children’s names?
They are adorable. I’m sure they’ll love their new baby sis.
Catharine? Larissa? Rachel? Who the heck names a kid Rachel?!!?
Now Swoorftilp, on the other hand, I quite like. 
Either Kaylee or Bailey.
I’m rather partial to “Marvin O’Gravel Balloonface,” myself.
