Here you go: Sasha and Vanessa
You can thank me 20 years from now when your daughters kiss your feet in gratitude for giving them both such lovely names.
And congrats!
George and Michael.
What? What?
Never Mind. 
Congrats.
We had a hard time with girls names and finally settled on Elinor for our daughter. We call her Nell. We stopped having children on the chance we’d have to come up with another girl’s name, so I’m afraid I’m no help at all.
Congratulations to you both!
I went to school with twins a loooong time ago when twins were pretty uncommon: Mary Katherine and Mary Elizabeth. They went by Kate and Beth.
My “traditional” suggestion: Patience and Prudence. 
Woah…
Those were two of the names I was thinking of calling my son if he had been a girl.
Holly and Corrine
I like Audrey and Vivian! My friend has twin daughters who will turn one this Christmas, and they are Audrey and Harriet. I like Audrey, but am not partial to Harriet. Vivian has a positive association for me too, as my best friend when I was five was Vivienne.
Here are my favourites of those already suggested plus a couple of my own:
Elizabeth
Catherine
Claire
Isabelle
Eleanor
Matilde/Matilda
Joanna
Genevieve
Gabrielle
Lauren
Clara
Victoria
Eloise
Imogene
Jocelyn
Thanks everyone. A bit surprised at the response. Will go through these with the family this weekend.
In March at the San Diego zoo, before we were expecting, saw twins that were barely todding wearing Dr. Suess Thing One and Thing Two shirts. I thought that was way cute.
Am reading up on the basic twin parent traps and how to encourage everyone thinking about them being two individuals rather than a pair.
China bambina orginally proposed Timon and Pumba as names, and we’ve not considered any twin pair names since then.
Those are both lovely names, but I’d be a little cautious about naming girls Andy and Sam. That seems a little too cute to me. I wish it were possible to keep from using nicknames.
My only idea is that the names should sound good together, and should probably have a similar “feel”, since they will be used together a lot. I’m not sure I’d go with Vivian and Brittany, or Grace and LaToya. Since you’re looking for classic names I doubt this will be a problem.
Ping & Pong.
I hope I have twins someday 'cause I really, really want to name them that.
and don’t forget…
Laetrille
Sucrette
Listerine
Moline
Codine…
I’m not helping am I?
My name is Kelly. Confession over.
Kelly was a kind of groovy name way back in the 60’s, very uncommon. My grandmother told my mum it was a boy name. She failed to tell her it rhymed with smelly.
I always longed for one of those “boy” names.
So my (imaginary, never happening) twin girl names would be, Stephanie or Steph and Phillipa or Phil (or at a pinch Charlene…na far to Neighbours)
I haven’t seen anything I like better than Audrey and Vivian. Ashes may have a point, but the names have the same kind of feel. They go together without the cuteness or novelty factor. Vivian and Dakota would be weird, but Audrey and Vivian works for me.
Same letters: Mia and Ami
Xmas names: Holly and Ivy
Patriotic: Carolina and Dakota
Congratulations!
I love the names you picked.
Irishfella’s neices have beautiful names (I think), they’re not twins, but the names go well together. They’re called Liviana and Alessandra, as their dad is Italian and he wanted something to remind them of their heritage. The names are traditional, pretty, feminine but unusual.
Other names:
Lucy
Hannah
Claire
Joanna
Tara
Michelle
Emilia
Dawn
Eva
Cora
Jessica
Jennifer
Caroline
Anyway, I hope you enjoy picking out some names, and hopefully our suggestions will help!
Denise and…
Deuddernise.
Or perhaps something from the Bible…
Cain
Baal
Onan
Nebbakanezzer
Satan
Tamar
Jezebel
Esau
Goliath
…still not helping.
You may not believe this (since you were obviously joking when you recommended it), but I actually know a Tamar. I’ve always wondered why, if her parents wanted to go with something Biblical, why not Rebecca or Elizabeth? Mary? Rachel? Anything but Tamar! Or Jezebel.
Tamar is not considered a bad girl in the Bible. Yes, she did the nasty with her father-in-law, but she’s considered justified (as is made clear by Genesis 38:26)because she was being unjustly withheld from marrying her rightful husband (which was her younger brother-in-law).
And the name means “date” or “date palm,” and dates are considered the exemplar of sweetness in Middle-Eastern cultures.
Penelope and Rebecca
If I was naming twin boys I’d name them Simon and Oliver.
See, my feeling on nicknames has always been “I WANT ONE!” I want a name that friends can call me that others wouldn’t, a sign of familiarity and with a name like Miranda, Andy for short, it isn’t soemthign that most people would think of and therefore could serve as that. My name’s Sarah and there really isn’t much in the way of nicknames for that it (well, my father insisted that people would call me Sally, but no one ever has and I doubt anyone ever will).
Also, with Samantha or Miranda, you wouldn’t fall into the problem that a lot of women have had, with names like Debrah, where everyone calls them Debbie and they don’t feel like they are being taken seriously. I have an aunt with that issue.
My two cents
