Mildly posh, long, classic girl's names?? Please help!

[YumMum94]

Hi! Three months till baby and I'm completely stuck for girl's names.
Big hitch is our surname, which is one of those ridiciously posh, like laugh out loud, old english surnames- think Cholmondley or Beaufort, double barrel it and you're there. I would love to use a flouncy, unusual name like Arabella or Seraphina but saying the full name out loud sounds like a made up posh person name.On the other hand a "modern" or (sorry) "chavvy" name really doesn't fit. We still want to go with a long name, preferably one with potential for nicknames.
For boys I've got Jonathan and Frederick. Both outside the top 100 but still classic and recognisable, with lots of shortenings- I can't stand calling babies long names.
Ideas so far:
Catarina: Love nns Cara and Tara, but the most obvious would be Cat, which I can't stand
Rosemary: Nice, but a touch too old lady
Cordelia: Love, but bit too posh, and dh's ex-girlfriends name
Sorry it's so long!!

Jemima

Tatum

Tabitha

Josephine

Elizabeth

Georgette Georgia

Lavinia/Vinny
Emilia/Emmie
Alethea/Thea
Georgiana/Georgie
Constance/Connie
Adelaide/Addie, Adele
Evangelina/Evie, Ginny
Aurelia/Rae

I like names that are formal and have a short, too - they give people options in adult life. Always good.

I love Tabitha and Henrietta, of those mentioned.

Ha, I wanted Seraphina for DD. I was overruled!

Hester
Maude
Sarah (goes with everything!)
Charlotte
Miranda

Florence
Meredith
Marianna
Vivienne
Monica
Persephone
Georgina

Hi!
I love the following:
Eloise
Evelyn (Could be shortened to Evie, which is just lovely)
Francesca
Rheannon (This is how my sister spells her name, I think it's quite classy- she goes by Rhea)

I hope you find something that suits!

Carolina
Evelyn
Evangeline
Miranda
Georgina
Danielle
Samantha
Penelope
Gemma
Genevieve
Virginia

I also love Beatrice, Hermione, Phillipa and Felicity that have been suggested

How about something classic but also slightly more 'of the moment', so that you can keep it fresh? (Apologies I'm not sure which names you would describe as 'chavvy'!)
How about;
Camille
Matilda
Margot
Elise
Edie
Elodie
Jemima
Avery
Astrid
Luella
Florence

Jemima is growing in popularity here.

Elizabeth is my favourite.
Annabel
Arabella
Grace (not long, but classic)

Rosalie - no one's had that yet!

OP, I don't know if this has already been mentioned, but I know an 11 year old Josephine who uses the nickname Fifi. If you like the name would you consider that?

Lucy i know it's short but it has a lovely ring to it
Elizabeth (Lizzie)
Victoria (Tory)
Camilla
Annabelle
Isobel
Eloise

Kathinka - pronounced Katinka

Dutch name but rather nice and different to your average posh name. Don't know how well it would go with your surname.

Have a look through the Torygraph's birth announcements to see the going UC names. Pretty plain really, though Arabella is in there with Elizabeth and Clementine.

I particularly like this for the hospital reference:
On 19th August 2015, in the Lindo Wintal reg, at St Mary's, Paddington, to Alexandra (née Munro Ferguson) and Nicholas, a son, Arthur Ralph.

Mine was more:
On xx date, out of my vagina vulva, onto a blood spattered bed to Sofa and Armchair, a son, Chaise Longue, a sister for Deckchair.

You asked about Davina. For very obvious reasons, I have name changed for this post!

I'm a Davina. I loved it as a name right up until the advent of Big Brother. Then I did feel it was cheapened somewhat. I already had a nickname (kind of a short version of Davina) at school amongst my closest friends, and so that's how I then introduced myself at uni. Lots of people still call me by the nickname, others by Davina (colleagues, other parents at DC's school, people I've met more recently).

The Davina McCall thing should be less relevant to your DD. She's not so much in the spotlight now and I am learning to re-like my name.

But it just goes to show that, whatever name you choose, you cannot at all predict who will come along in 5, 10, 20 years time and create new associations for a name. So, if you like it, go for it!

Ooh how about Arabel as a shorter alternative to Arabella? Or Mirabel.

Henrietta
Annabella

With a very long surname, a shorter first name would be better?

Eliza
Elena
Kirsty
Eloise
Esme
Elspeth

I think - if avoiding "chavvy" names is your objective then you need a very classic name. Lots of "chavvy" names (in my opinion) are where people are trying too hard, especially if you have to double barell a surname. Some of these more unusual suggestions sound a little "wannabee" - which is what makes it "chavvy" in my humble opinion.

I think Anna, Lucy, Elizabeth, Grace are all good suggestions.

Katherine/Catherine is a good name. It's a classic name that is never in style or out of style.

It can be shortened to a variety of things to suit different personality types. (She may be a Kate, Kathy, Katy, Kitty, or even a Cat sort of person.)
