Girl's names - to go with sibling Holly, fairly short and easy to say/spell?

[DueinSeptember]

Any ideas? Surname is a normal british name, beginning with 'M'.

I'm not fussed on long names, would prefer one or two syllables, three at the very most. Would like something which is not that popular, but not too far out.

So far I like Tabitha, Robin, Poppy, Lowri - but none of them are 'right'.

Baby will hopefully be born in September. I chose Holly for my daughter because she was due in December.

Thanks.

Thanks everyone:

Out of the lists I like:

Autumn -like it but worried it's not name-like enough though
Lorna - quite like it
Sylvie - same as above
Kate/Katie - love it, but worried it'll become too popular with Kate Middleton
Lara - like it but strong Welsh accent will make it sound bad
Lucy - like it, but close friend is called it.
Amber - like it but unsure, in a similar way to Autumn.
Tara - same problem as Lara
Anna - Close family member's name

Also like Emma, Laura but they are very much of my generation.

Tamsin
Meryl
Louisa

Rose?
Lucy?

Willow

Oooh, OP, Sylvie is the name I want for if I have another girl.

Go for that one!

Ruth? Rebecca?

Ffion is a really pretty name. As is Angharad.

Also really like Sylvie. And Emma is very nice too.

Molly or Polly

no....

Esther
Nina
Phoebe (bit popular?)
Carys

Thanks for the further suggestions. I like a lot of them, but strangely a lot of them are close family and friends names (even one very close to my name!).

I spent last night on some american website called nymbla which suggests names based on names you already like. Just ended up going round in circles.

September is a name but personally not keen and it's long.
Kaeya (Ky-a) is very pretty. It is a name that refers to Indian monsoon season which goes from June to September.
Saphire is the birthstone for september

Keira
Miranda
Abigail (Abi)
Naomi

Medi? It's Welsh for September (I think!)

Easy to spell, not massively popular but not 'out there', mostly one of two syllables:

Anita
Nadia
Ursula
Iris
Imogen
Violet
Pearl
Anna
Gail
Faith
Libby

DD1 is Abby
Also liked cassie, cara, carrie, Isabel, Georgie, indie, Isla, Keira, Libby, layla, maddie, neve, Maggie, ruby, Seren, sasha, sadie, tess, Jen, jess, bekah, willow, maisy

Heidi would go well with Holly.

Sorcha
Tamsin

I know a holly with a sister called lily. Think that's a cute combo!
