Opinions on my top 10

Bin Willa and Honor.

Ottilie - fussy and otterly, not very pretty sounding tbh
Margot - fine
Hazel - fine
Daphne - fine and a bit different, some may find it wet
Esme - dull and people get their knickers in a twist re. pronunciation
Willa - sounds half finished and wishy washy
Clara - fine
Honor - "on her", no teenage girl will thank you for the name
Iris - fine, quite nice but will date
Mabel - won't date well

Ottilie twee and faddy
Margot looks like maggot
Hazel frumpy
Daphne hideous! She won't thank you.
Esme nice
Willa absolutely awful
Clara meh
Honor ok
Iris nice
Mabel nice

Ottilie - horrible. And it will get (inexplicably) popular due to Zoella
Margot - maggot
Hazel - quite sweet
Daphne - ok
Esme - nice
Willa - very nice
Clara - nice
Honor - as long as your surname isn't something that you could be "on".
Iris - dreadful
Mabel - old lady

I like Iris, Hazel and Honor.

My daughter’s name is on this list! I like lots of them,but am not keen on Ottilie and Mabel. They sound a bit try-hard to me(sorry to others who’ve used them-can see that the name I chose is not everyone’s cup of tea from responses !).

I love the name Ottilie and don't associate it with Mumsnet at all - it reminds me of a short story by John Wyndham. It was one of my top girls' names. I also like Iris and Margot from your list.

Ottilie - don't like
Margot - not keen
Hazel - ok
Daphne - ok
Esme - not keen
Willa - don't like
Clara - don't like
Honor - ok
Iris - ok
Mabel - not keen

Hazel, Honor or Iris

My German penpal was called Ottilie. It was pronounced Oh-teelya. I'm wondering if the same pronunciation is used here?
Never much liked the name anyway.
Mabel - yes
Clara-ok
Iris - bit 1950s housewife, but yes
everything else, no

Ottilie - lovely but very popular
Margot - dislike
Hazel - ok
Daphne - lovely
Esme - ok but hate it said Ezmae
Willa - not sure, prefer Willow
Clara - lovely, my fav
Honor - lovely
Iris - ok
Mabel - ok

Ottilie - don’t understand the current fad for this. Frilly. That said, I do like Ottoline.
Margot - A bit trendy. Don’t mind it, but not for me.
Hazel - want to love but can’t shake the dowdiness.
Daphne - dislike
Esme - love pronounced Ez-mee. Like pronounced Ez-may.
Willa - Willy. Another one I don’t get.
Clara - Love
Honor - Love
Iris - fine. Used to be on my list but so popular where I am atm, Ivy and Iris are feeling like the new Evie.
Mabel - Been warming to this recently but feel it’s a very go-to hipster name.

I love Ottilie!

This list is one of the most mumsnetty lists I’ve ever seen

Hazel’s best friend is Beverley and they have crap perms and nick cheap jewellery from C&A on a Saturday morning. Then they stand outside HMV and have a fag.

I like Honor and Clara the best from your list.

I like Willa, Cara, Honor.

I'm not bothered by popularity as such either OP, but I'm less keen on trendiness, such as the current vintage/retro name trend which most of your choices unfortunately fit - as I would worry they may date more (if mostly only very elderly or very young women have the name). Despite that, I do like the sound of:

Iris - as it's both classical (Shakespearean/Greek Mythology) as much as retro/floral
Clara - such an elegant but pretty sound imo
Esme - ditto, especially the Ez-May pronunciation
Honor - very classy

I don't hate Hazel or Willa either, but Margot, Ottilie, Mabel and Daphne are really not my cup of tea, sorry.

Hazel and Iris are both very nice. Dont like any of the others very much. Willa and Ottilie are both especially dire.

Honor and Margot are my favourites (I'm assuming like Margot Robbie?).

Ottilie - really pretty but makes me think of otters
Margot - cool and classy
Hazel - sometimes like it, sometimes don’t (certainly fits my style of names though)
Daphne - love love love!
Esme - lovely
Willa - much prefer Willow
Clara - beautiful name
Honour - meh, doesn’t sound like a name to me
Iris - gorgeous
Mabel - my favourite name of all time

Overall your list is really nice and very much my taste

Ottilie- blah, trendy will date
Margot- getting popular; sure nice name not to my taste
Hazel- fine
Daphne- love
Esme- ok
Willa- like, something I can’t get on board with though
Clara- love, classic, pretty, elegant and timeless
Honor- less keen
Iris- love this and meaning
Mabel- like a lot

Love: Hazel, Daphne, Iris

Like: Clara, Honor

Not fussed: Esme, Ottilie, Mabel

Can't stand: Margot, Willa

Think we’ve got similar taste
Ottilie-not sure how to pronounce
Margot- never met one but so pretty
Hazel- imagine quite a sensible wee girl or unfortunately with cancer (fault in our stars)
Daphne- pretty but too entwined with a pony doo with me
Esme- really gorgeous and sophisticated
Willa- not quite for me but a cool name
Clara- gorgeous and don’t know many
Honor- similar vibes to Hazel of a sensible girl in glasses reading a book
Iris- my favourite! really pretty and cool girl vibes
Mabel- sweet for a child then works for an adult too

Ottilie - love
Margot - love
Hazel- like
Daphne - no for me
Esme - like but popular
Willa - like but too open to teasing
Clara - love
Honor - love
Iris - love
Mabel - like

Great list @everly lots of these were on my list for DCs
