Nearly there…Seren

Stella is popular in Italy now - that's literally just the word for "star" there too. Plenty of word names are used in lots of languages. New ones sometimes sound a bit weird to older speakers, but it's not a reason to avoid Seren, I don't think.

Seren is lovely.

How about Anwen or Cerys

@MolkosTeenageAngst , the word for white changes depending on context, so although I'd say white quite a lot, I'd say gwyn less frequently.

English people can’t pronounce Seren or Eira, won’t that bother your DH ? If you want a Welsh name I would choose one that can be pronounced easily in English. If you have an estuary accent then you will find it hard to sound either of those names as the sounds will be so unfamiliar to you.
If you wouldn’t call your dd Star then why Seren ? As it is literally star.
I really like Edith from your list, and think it is more elegant with Julian than Seren.
I also like Constance. The meaning is so beautiful.

The word white is used a lot but doesn’t stop Gwyn being a popular Welsh name, I would say I use the word white more often than I use the word star.

@3ormorecharacters , it's because it's a word that is used quite a lot. Like you're a star, five-star, pop star, film star, shooting star, or gold star.
I only use a word like rose or daisy when referring to the flower, snow when referring to snow, and roman when I'm referring to Rome or something like a road or architecture.

Foxgloves have lots of different names, and which name is used probably varies by region. I call them bysedd y cŵn. Ffion is a pretty name.

If OP likes Seren, there's no reason for her to name her child it, but like a pp, I don't think it particularly goes with the sibling's name.

One of the things I really like about Welsh names is how many are nature based. Like Eira, Ffion, Enfys, Haf etc.

What about Ffion? DH and I both love it but can't use it for family reasons.

Tesni (TESS-nee) is nice too, means the warmth from the sun.

Nia, Cadi, Alys, Mari, Mali are other Welsh names I like.

Of your list, Eira is my favourite. Pronounced EY-ra (ra for rabbit). Although in my accent hey and hay are pronounced the same. People will mispronounce as ruh instead of ra. My Welsh name gets mispronounced constantly so most Welsh names will have the same issue.

Seren is nice too. You're in England so most people won't realise that Seren is literally the word for star in Wales. As a PP mentioned, we use Rose, Ivy, Daisy etc.

Seren is a popular modern Welsh name and one that is used in Wales, nobody will think it strange just because it means star. I think you’re overthinking and it doesn’t matter that you wouldn’t call a child Star in English, the meaning doesn’t make the name naff. You wouldn’t call a child Foxglove in English but Ffion is a popular Welsh name and Eira is on your list but I’m assuming you wouldn’t call a child Snow in English either? Gwyn is a popular Welsh name that means white and Bryn means hill but I’ve never met an English boy called White or Hill.

Names that have a common meaning are fairly common in English; Rose, Lily, April, Summer, Faith, Willow etc. They won’t necessarily all translate into a usual name in another language but I don’t think that really matters, if you pick a Welsh name and its meaning in Welsh isn’t a name in English that’s honestly fine. Go with the name you love and don’t overthink whether it can be directly translated from Welsh into English and still be a name.

I like Seren. Some Welsh girls names I like that would be pretty understood how to say in the rest of the UK are Eleri, Nia, Nesta and Lowri and Bethan. I particularly like Lowri. Also Gwen is nice. Of your other choices I like Connie.

(I'm clearly biased!)

Fair enough, OP, and I agree re Cat, Cath and Cathy but Kate, Katy, Kitty are fab, as is the full Catherine.

@DacwMamYnDwad I'm not sure what the distinction you're making is? Besides, there are plenty of names with a literal meaning in other languages or even in English (e.g. Roman, Daisy, even Grace!) and no one thinks it naff or weird.

It's a lovely name

Catherine Grace.

Beautiful!

@ReindeerGames , it doesn't mean star, it's the actual word star.

I think Seren is lovely. I first came across it about 12 years ago as a friend's little daughter was called Seren (not Welsh), and then there was a cute bat called Seren on a Cbeebies show -abadas I think.
There are so many names that mean a word in another language, I think it is fine.

@QuietYou , Eira.
It's like EY-ra (Ey like in Hey! not Hay, and ra like in rat, not ruh). It doesn't really sound like Ava with an r instead of a v.

I'm not keen on Seren and would put it in the same category as Karen and Lauren.

I think Seren is lovely and goes ok with Julian.

I know old lady names are having a revival but I don't like Edith.

Of the others, Constance would be my fave but if you love Seren, just go for it!

I'm biased, and I admit this, but I loved the name Seren so much... that I named my (male, yep; know it's a female name!) dog thus. And then, when he was 13 and dying, an old school friend's wife was expecting a daughter (their second) and they decided to call her Seren. Possibly after my much-mentioned, beloved hound... but more likely because it's a beautiful name. I'm mostly Welsh, they're not - and we live in Surrey!

I already had a completed family, and our dog was meant to be female so I'd allowed my 9 year old (at the time) to name it... but the puppy who bonded with my then-1 year old was male, yet my oldest had set her heart on Seren for its name...

If Seren was on your list for the first baby... and you both approved it... use it for your first daughter! It goes well with Julian. Don't think so much about the meaning behind the name. My name translates as "light", my daughter's as "pure" and my son's...? "God's gift to mankind". We're all anything but what our names translate as!

I have a Serena, so when I see Seren, it just looks a bit odd to me! Lovely name though.

I'm not sure what the issue is with it meaning 'star'. Almost every non-made up name has a meaning of some kind, some pretty obvious in English (e.g. Rose) and no one generally thinks it's naff. I'd say Star is quite a nice association to have with your name!

If it's good enough for Tom & Natasha Archer ...
Or alternatively Nova?
