Ethereal/fairy names

[Ginnywoofly]

Dd1 has nickname Pixie (not related to actual name but she is very pixie like) and dd2 is likely to be very fair. We are looking for an ethereal/fairy type name (not too “out there” but unusual/maybe vintage style) that conjures up images of nature, Celtic folklore (Irish surname so open to Irish or possibly welsh suggestions) magical forests, nymphs, or maybe an underused flower name. We have Scandinavian heritage so a Scandinavian/Nordic folklore name could be good. We want it to be like a Disney princess/lord of the rings style name, but an actual name not made up/obviously named after a character. This is what we have so far:
Althea
Dorothea
Gwyneth, Gwendolyn
Arwen, Ariel (similar sound to these but real name suggestions?)
Fae, Faith, Effie
Tatiana/Titania/Tiana
Flora or Frida
Lilith/Lilian
Felicity
Sylvie
Elif (we have no Turkish background)
Elinor or Elin
Elodie, Melodie, Eilidh, Elsa, Elspeth/Elsbeth
Laurel (suggestions for similar real name?)
Morwen, Marion, Miriam, Merida, Mara, Mabel
Katja

Any other suggestions/feedback?

The only one I don't like is Althea. All the others are lovely!!!

Do not name a child Phaedra! In Greek mythology Phaedra fell in love with her stepson and when he rejected her she lied that he raped her and he got dragged to death by horses.

Sylvia
Lucia
Bronwen
Cecily/Cicely (like Cicely Mary Barker)
Elowen
Violet
Lisette
Hilda
Enide
Lunete

Sephryn?

Aeryn, pronounced Air-in. It comes from the name Erin, so it has Irish links, but it is also a very minor character in LOTR I believe, and it has that LOTR feel to it, like Arwen.
I think it's beautiful.
I also really like Daphne and that has a fairy, woodland feel, but a bit more vintage. You can't go wrong with Sylvia/Sylvie either.
I don't think the name Lorna has the feel you are looking for at all personally.
Good luck choosing, I love your criteria!

Some Welsh names below. (I also like names with an ethereal sound). I would make sure you can pronounce any unfamiliar names properly though before use and check you have got them right. Baby name sites sometimes suggest random Welsh words as names, such as snake, wheel and torture!

In Welsh the emphasis is usually on the penultimate syllable and names ending in Wen (pronounced when) are feminine, and wyn (pronounced win) are masculine. So Bronwen is a female name and Bronwyn isn't a name but if it was, it would be masculine.

Esyllt - this is Welsh for Iseult. It's hard to say if you're not a Welsh speaker due to the aspirated L - Ll. The Cornish version, Eseld, is easier to pronounce.
Eira - Welsh name meaning snow. It's pronounced EY-ra - ey as in hey and ra as in rabbit.
Eiry - same as Eira but with a ree instead of a ra.
Eirlys - snowdrop, EYR-liss.
Enfys - rainbow, EN-viss.
Ffion - foxglove, FEE-on (on as in opposite to off)
Aneira - anne-EY-ra
Nia - NEE-ah, Welsh for Niamh - in Irish Nia Ben Aur and Osian are Niamh and Oisín.
Eleri - EL-erry (to rhyme with Kerry). See also Teleri and Meleri.
Mari - one of several Welsh versions of Mary, pron. Marry.
Seren - SEH-rehn, en as in hen and the same short e sound for the first e. Welsh word for Star used as a modern Welsh name. Cornish version is Steren.
Morwenna - MORR-wenna. A welsh and cornish name. In Welsh we roll the R but I think the Cornish don't (I could be wrong).
Sabrina - not really Welsh but it's the latinate version of the Welsh Hefren, the goddess of the river Severn.

A few other names:
Ishbel
Iseult/Isolde
Elowen
Fay/Faye
Mara

You can hear some of the names I have suggested pronounced at the above link

Willow
Esme

Wow aren't Welsh names beautiful!

I went to school with an Arwen, she really suited the name!

Elvira

I love Elodie and it was on our possible list

Yes it's lovely to have an airy fairy name for a girl up to the age of around 9 or 10 I'd say. Also try thinking a bit further ahead in what you'd like your DD to have on her CV

Just saying.

Peri/perrie queen of fairies?
Rhiannon
Eleri
Mali
Lily
Farrah
Mabli

Merryn (Cornish - means something to do with the sea), Rhoswen (Welsh, means white flowers) are two of my favourite Celtic girl names.

Love Elin and Eilidh. How about Aileen?

I also adore Marion. Laura but with the Italian/Spanish pronunciation (Lau as in allowed)?

Moana

*Do not name a child Phaedra! In Greek mythology Phaedra fell in love with her stepson and when he rejected her she lied that he raped her and he got dragged to death by horses.
*That's hardly going to happen to this child,

I love Effie

I read like so many on your list. Of those suggested I like Maeve, Rhiannon and Isolde the best :)

Pipany

Thinking about your Norse side: Katla, Freyja, Embla, Maya/Maja

Eswen

Sylvie is a beautiful name I think.

I forgot Tesni (TESS-nee) which means 'the warmth from the sun'.

Aurora or Wren

I know an Elspeth who gets called Effie, but you could call her Elfie.
