Shorten our long list

Cross out all the ones that end in 'ie' (they are often diminutives and a bit cutesy) and see what you have left.

Also, dotty means crazy where I come from, like batty or loopy.

I'd use Dorothy instead.

Zara is lovely. Love Eva too but there are a lot of babies called Eva/Evie

Dora, - the explorer
Dotty, - no, weird name on an adult
Ada, - nice
Ivy, - nice
Zara, - nice
Stevie, - as a nn for Stephanie
Bobbie, - a nn for Roberta (meh)
Grace, - fine, very popular
Marnie, - ok
Sasha, - ok
Penelope, - meh
Ottilie, - potential to date?
Mathilda, - nice but spell Matilda
Iris, - very popular and of this time
Sarah, - much more traditional that most of the others in your list
Coral, - no
Ruby, - ok
April, - not if born in April please
Tara, - dates
Poppy, - a bit twee
Nellie, - elephant
Lottie, - nn for Charlotte
Millie, - nice
Martha, - lovely
Eva - very nice, popular
Thea - nice but potential to date
Nancy - ok
Theadora - no
Cerys - nice (are you welsh?)
Vitoria - will forever be correcting from Victoria
Catriona - as long as you realise this is pronounce Katrina
Micheala - nice, not that popular at the moment
Mollie - nice if a bit frilly
Rainey - not a name
Phillipa/ Pippa - nice, use Philippa (that spelling) with nn Pippa

Zara
Sasha
Iris
Catriona
Michaela

Ottilie butterly
Ottilie ridiculous

Rainey day

Dora, - the explorer
Dotty, - full name Dorothea would be cool

Really dislike the following:

Catriona
Micheala
Mollie
Rainey
Phillipa/ Pippa

I like Iris, Penelope, April and Pippa

I like Nancy, Zara Iris and Molly and love Cerys. I have a Carys!

Dora - The Explorer
Dotty - What you call someone who is losing their marbles
Ada - Not as nice as Ava
Ivy - Lovely, but very "in" at the moment so might become faddy
Stevie - Works better as a nickname, but I don't like Stephanie
Bobbie - See above; traditionally short for Roberta, which I don't like
Grace - Beautiful, timeless
Marnie - Bland
Sasha - Lovely
Penelope - See Ivy, but I like it less than I like Ivy
Ottilie - Not a fan. I just see otters.
Mathilda - Miles better when spelt Matilda. The H is unnecessary. I love this name.
Iris - Not a fan. Makes me think of eyes.
Sarah - Beautiful, timeless, and underused now.
Coral - Awful.
Ruby - Quite nice, but has been obscenely popular where I live for going on 10 years now.
April - Not a fan.
Tara - Outdated.
Poppy - Too trendy/popular.
Nellie - The Elephant
Lottie - Lovely when short for Charlotte
Millie - Lovely when short for Amelia/Emilia
Martha - Love this
Eva - Not a fan; prefer Ava
Thea - Lovely, but mispronounced as "fea" by a lot of people.
Nancy - Not a fan
Theadora - Should be "Theodora". Not a fan, but it's a good way to get to Dora if that's what you want.
Cerys - Not a fan
Vitoria - Name of a coffee brand
Catriona - Not a fan.
Micheala - Should be "Michaela". Not a fan. Outdated.
Mollie - Better when spelt Molly, but I still don't like it. Prefer Polly.
Rainey - Absolutely not.
Phillipa/ Pippa - Not a fan.

I would shorten it to: Ivy, Zara, Stevie, Grace, Sasha, Penelope, Mathilda, Iris, Sarah, April, Eva, Theodora (spell it this way), Cerys, Catriona, Nancy, Michaela, Victoria, Mollie, Philippa/Pippa. Still a long list, and I could shorten this to favourites, but these seem the most usable and appealing to me.

Cerys is my favourite on your list.
Carys is a nice alternative as well

You might want to check your spellings of some of those... Michaela, Theodora and Philippa being the usual versions.

There's a lot of different name styles on your list from vintage to cutesy to modern to classic, so maybe deciding what style you prefer would help narrow it down.

Iris, Nancy, Matilda and Martha, Zara.

Vitoria-Very strong and elegant
Catriona- Very exotic and sensual
Michaela-Very romantic and feminine
Sasha- Very sweet and soft

This is from an American perspective with Latin and European roots.

Good luck and congratulations!

Theadora (or Theodora or Dorothea) - then you can chose your favourite nickname from Dotty, Dora or Thea.

Nellie or Nancy

Is there anything that points you towards some more than others? Eg ability to be shortened or not and popularity?

Dora, - not keen- makes me think"the explorer"
Dotty, - also not particularly keen as a full name.
Ada,- like
Ivy, - like
Zara, - like
Stevie, - love as a nickname but not sure as a full name for a girl.
Bobbie, - love. For me is more a boys name though might be just as was our top boy name choice.
Grace, - love
Marnie, - not keen.
Sasha, - not keen.
Penelope, - seems quite popular at the moment. Have heard pen and penny as nicknames. Is ok.
Ottilie, - not really keen.
Mathilda, - is ok but would be shortened probs to Matty or Tilly.
Iris, - like.
Sarah, - ok. Bit boring.
Coral, - not keen.
Ruby, - like.
April, - not keen but personal experience of person I think!
Tara, - not keen
Poppy, - love
Nellie, - love
Lottie, - ok
Millie, - like.
Martha, - not keen.
Eva - like but very popular.
Thea - ok
Nancy - not keen.
Theadora - ok.
Cerys - ok. Makes me think Cerys Mathews
Vitoria - not keen
Catriona - ok.
Micheala - bit boring.
Mollie - ok
Rainey - not keen.
Phillipa/ Pippa - love.

Sasha
Ruby
April

I love Ivy but have heard too many recently.

One way to thin your list out would be to get rid of all the names that are diminutives or nick names, and only put them back in, if you like the full length name, Lottie, Bobbie, Dotty, Nellie etc etc.

Personally, I wouldn't use April for a baby born in August.

Check out the lists of most popular names in the last couple of years, to avoid your child being Eva number 7 in the swimming class!
