Shannon or Celeste

Its just dawned on me these are the names if the Watts mum and daughter (the killer nect door)

Celeste - beautiful, love nickname Cece too
Shannon - hideous, dated, 90s school bully name
Fallon - hideous, reminds me of penises for some reason (??!!!), sounds like the name of a character on a show like 16 and pregnant (may actually be)
Juliette - beautiful!
Eden - lovely
Arden - no, what?!
Dixie - cute, i like as a nickname for Beatrix. Then you can have nickname option Bea too, also very cute

Don't like either...

That Netflix show is out ages, I watched it a few months ago. I think if she were naming three kids Shannon, Bella and Celeste it would be valid but naming just one of those names is ok.

I like Celeste. It reminds me of the Babar cartoon series which I used to watch on Tiny Pops with my younger siblings. Also Celeste from Animal Crossing.

They are two names of the victims in the Chris Watts murder case (she spelt it Shan’ann but close enough). Many people in the UK won’t have heard of them yet but the Netflix show about their murder, American Murders, lands here soon and it will be well known then. That was my first association when I saw them. I think Celeste is a nice name though, Shannon not so much.

Celeste is quite nice. Doesn’t especially remind me of the pill.
Shannon is low rent 90s so I wouldn’t.
Fallon - no, made up/downmarket
Juliette - lovely, though prefer Juliet
Eden - overused, down market
Arden - not a name
Dixie - could be a nice nickname though but low rent as a full name
Seren - lovely but getting super popular
Noelle - OK

Other thoughts

Meredith, Lois, Arran, Ffion, Marianne, Laurel, Elowen, Cleo, Ines, Juno, Caitlin, Linnet, Roslyn, Rosen, Stella/Estella, Merryn, Cerys, Aster, Emerald, Elen, Frances, Circe, Olwen, Sylvie/Sylvia, Aislinn/Aisling (Ash-lin/Ash-ling), Astrid, Cassia, Adela, Serena

Also Erin, Robin, Rowan, Iris, Margot but they are all super popular
Astra - another star name, though people might find it funny right now...

Celeste is a million times nicer (and the birth control pills are Cilest and no longer manufactured sadly so won't be an issue as your child is growing up).

Celeste, Noelle and Juliette are nice.

Shannon is awful, very much in the Sharon/Tracy/Kevin mould.
Celeste is really nice - I would never put those two together as similar names

Natasha?

Shannon is the Sharon/ Tracey of the late nineties/ early 2000s.

Fallon sounds a bit Dallas to me

Fallon Carrington Colby was actually in Dynasty. She first appeared in 1981, apparently. I think we are meant to infer that the only other Fallon I’ve ever heard of (in the Archers) was named after her.

So, a bit dated?

I think a lot of names depend on the beholder too. i know a 24 year old Shannon who is by MN standards from a trashy background, single parent family, multiple siblings from different fathers. Went to school with DS. But smashed her exams, was confident and musical, went to uni, now has an enviable and quite glam job. She owns her name and herself and isn't in the least trashy. So I associate the name with her!
I know another Shannon slightly less well who is a geophysicist.
So of the two I'd say Shannon!

You have quite ‘dated’ taste, OP. I don't mean that unpleasantly, but these all sound as if they were popular quite some time ago, but not long enough ago to have come back. Juliet is the nicest by far.

The pill is Cilest so at least spelt differently. I wonder if people avoid Yasmin for the same reason.

Celeste - footballer's daughter sort of name
Shannon - no
Fallon - just no
Juliette - lovely
Eden - no
Arden - no no no
Dixie - Jesus, please say you're joking

Celeste, Noelle and Juliette are all lovely.

Shannon, is OK, but am from Ireland so we associate it with the airport and river.

Fallon sounds like a paint.

Juliette, it's lovely.

Eden is lovely too.

Arden is like Elizabeth Arden

Dixie....... Whistling Dixie

I love Shannon and Fallon is gorgeous. I don't really have any opinion on Celeste. Also love Eden from your new list.
You seem to be like me and have a very wide variety of naming styles. You wouldn't typically expect someone who likes the name Shannon to also like Juliette. You couldn't two more extremes if you tried.
Shannon certainly doesn't have to be a No just because a few people on Mumsnet don't like it.

Although Erin isn’t dissimilar to Shannon but is much nicer and doesn’t have the same connotations.

Celeste. Definitely not Shannon!

Seren is the only one you've mentioned that I'd consider, tbh.
For the love of God not Dixie!!

Celeste - very pretty
Shannon - meh
Fallon - noooope
Juliette - I like Juliet but not Juliette, just a tad unnecessarily frilly
Eden - ok
Arden - seems a bit made up
Dixie - nah, bit tacky.
Adriana - gorgeous
Noelle - nice

I think I'd go with Adriana tbh. Very diverse list!
