What do you think?

Sorry... EleAnor, with A, not O.

Wonderful names, OP!
My favourites, in no particular order, are:
Eleonor
Florence
Dorothy (Dottie)- There's a 7-year-old Dorothy/Dottie in my DCs school. I love her name.

I also love Frances and Pearl, my cousin's kids' names.
Vanessa and Samantha as well.

Absolutely wonderful list. Alice and Eleanor are my favourites.

Alice: classic, lovely
Eleanor: see above
Anna: see above
Isobel: girly, pretty
Florence: trendy, beautiful
Dorothy: trendy, little bit old lady
Edith: trendy, old lady
Beatrice: trendy, old lady, pretty. Like Bea as nn

Alice

As pp have said on this post El names are all the rage atm and best to be avoided. Ella and Elsie are top 25. Eleanor is 52, Ellie 63. Elizabeth 55. Eliza 38. Ella 13.
There definitely was a big Ellie phase a few years ago and it looked as though it was settling down but with the resurgence of 'Eleanor' it makes me wonder if Ellie is about to take a last gasp of air in the form of a nickname before hibernating for the next 50 years. I hope this doesn't come across as mean I'm not an anti ellier and can think of a few cool Ellies (UP, holocaust survivor Elly Goss, etc)...just an opinion. Feel similarly about other twee names lily, Gracie, Isla, mia, evie etc

Florence or Anna. Lucy is a fab name too, underused and goes with your tastes.

Lucy Eleanor
Florence Anna
Alice Isobel
Alice Eleanor

Alice my fave from your list

Alice, Edith and Florence are my favourites. Anna and Beatrice are ok. Isabel is everywhere.

I only like Florence

Anna and Isobel are the most timeless, there's Annas and Isobels of every age.

I have to say, I do not agree with this!

Anna, sure, but I have never met another Isobel my age (40s), and I have lived and worked in the Antipodes, the UK and NY.

For the first time ever, I have a colleague called Isobel, but she’d be early 20s, so one of the first people to be given the name in its most ‘recent’ surge of popularity, beginning in the 90s.

IMO, it is definitely not timeless, it is very cyclical. No-one, but no-one was being given the name in the 60s, 70s, even 80s. It was considered very old-fashioned, and not in a good/‘vintage’ way!

To be honest, I’d say it’s ‘done’ for this cycle, so if you’re after something more genuinely timeless, I’d avoid.

Beatrice & Isobel.

Alice

Almost all names are ‘dated’ because people associate them with the time period when they were most popular. As someone said above you either have to go very unusual (although you still run the risk of a surge in popularity) or very classic with a similar number of that name in every age group. I think of your choices Anna and possibly Eleanor are the only ones because the rest are more popular in this generation than for previous ones. Personally I’d just choose what you like and don’t worry too much!

A lovely collection of names. My order would be:

Alice
Edith
Beatrice
Florence
Anna

Eleanor
Dorothy
Isobel

I love the name Eleanor but it's a spelling nightmare. I've spent the past 40 ish years having to spell my first name and it's tiresome. It's not even a name that has lots of variations. Dorothy and Isobel I'd avoid because I prefer names with definite endings. I realise Anna doesn't fit into that and goes against my dislike of girls names that begin and end with a vowel but it somehow feels stronger than many of those names.

Oh and if the thing that most worries you is the name dating, then I'd stick with Anna (first choice) or Alice (2nd choice as currently more popular) - they are fairly timeless (although the only true timeless name for girls is Elizabeth - Sarah, Maria, Catherine, Alice and Ann/a have always been fairly well used). Eleanor and Isobel are very classic but have gone through more popularity surges, partly because of their soundalike variations.

Dorothy
Alice
Beatrice
Florence
Isobel
Eleanor
Anna
Edith

Absolutely lovely names OP!

Eleanor isn't faddy it's a classic BUT but but IMO it is tooo trendy atm to use.

Can we all agree to calm down on the El names for girls for a bit?

Ella, Elsie, Eloise, Elodie, Elly, Ellie, Elinor, Eleanor, Eliza, Elizabeth.

Then there are the E names. It wouldn't surprise me if we have tonnes of Emilias and Elivias next.

On namenerds on Reddit the top selected baby girl name for 2 consecutive years particularly with US moms has been Eleanor.

I would go with Anna, Alice or Florence.

1. Alice - ultimate traditional Engish name, never out of fashion, just prefer other choices.
2. Eleanor - classic and great namesakes but very popular (along with Ellie)
3. Anna - beautiful, elegant classic, simple and international too- use it!
4. Isobel - gorgeous but will have spelling issues because of soundalike Isabel/le)
5. Florence - a bit old lady trend but made cool via the singer and has a nice sound

1. Beatrice - slight old lady but very useable because of Dante and Shakespeare refs, plus cute nn Bee!

Drop Isobel - it should be timeless, and kind of is, but it has been so horrifically popular the last decade that it's just too much. There's also the spelling thing - Isobel, Isabelle, Isabella - the playgrounds are awash with Izzys and Bellas.

Same for Eleanor. It's lovely, BUT she will be Ellie and there are a billion Ellies absolutely everywhere.

Alice I don't particularly like, it seems prim to me, and slightly boring - I put it with Emily.

Anna is perfect.

Florence
Alice
Beatrice
Isobel
Eleanor
Edith
Anna
Dorothy

From your shortened list my favourites in order are:

Alice
Anna
Isobel/Isabel
Eleanor

I think you are quite right about those four being the most timeless.

I have an Isobel! Not keen when people call her Izzy though.

I love Eleanor (Nell)

I'm an Isobel! With that spelling, she will have to spell her name everywhere she goes just as a warning Haha! It's also quite common now. My favourite was Beatrice, but I also think Alice is such a sweet classic name.

I love Eleanor and Alice and like Anna and Isobel.

Don't like Beatrice, Dorothy or Edith much.

Alice
Anna
Isobel
Eleanor
Florence
Beatrice
Dorothy
Edith

Would be my order of preference. Names that date tend to be names that have risen very quickly. The Darkgreener website is fantastic for visualising this, so for example for Dorothy it has risen very quickly, and will end up falling in popularity when the next name trend comes in.

Names that don’t date generally are either very rare names, which fall outside of name trends, or very classic names which have always been around for all ages like Charles or Elizabeth. I would avoid the vintage name trend if you want a name that won’t trend. Twenty years ago they would have been widely seen as too dated to use, and in another twenty years the same will apply to them.

Isobel and Florence hands down!
