Girls names help

[Cocomelons]

Hi,
Really struggling with settling on a girls name for DD2. DD1 is an Isla. Surname is fairly long. We have the below list. What are your opinions on them?

Sienna
Halle
Phoebe
Darcie
Isabelle
Polly
Marnie

Thanks

Sienna - goes well with Isla.
Halle - no.
Phoebe -yes.
Darcie - no.
Isabelle/ not spelled like this. And too similar to Isla.
Polly- like
Marnie- no.

My favourites are Phoebe and Polly - both lovely.
Darcie is okay
I dislike Sienna and Halle as they are very trendy and rather bland to me. I dislike Marnie because I think it sounds awful.

I like Marnie the best. A nice list, really like Polly and Phoebe too

Isla is a pretty name, Sienna goes well with it.

Sienna - not keen
Halle - no
Phoebe - like
Darcie - dislike
Isabelle - overused
Polly - love
Marnie - not keen

Phoebe and Polly get my vote.

Sienna is my fave. I think it sounds nice with Isla too..

Sienna is pretty.

Polly is by far my favourite. Marnie is also ok. I wouldn't use Isabelle with Isla. Phoebe I personally dislike immensely but know it's popular with lots of people.

Halle & Polly are lovely.

I like Phoebe too

I love Darcie (would have spelt it Darcy though) my DH vetoed it though. It seems to be a marmite name.
