DC3 and looking for classic names

[Moopsy]

Hi ladies,

We have 2 gorgeous daughters Josephine and Iris and we are now TTC for dc3. I'd love a beautiful classic English name but not too popular. I feel I did well with Josephine but failed a bit with Iris as while it is beautiful, it is becoming increasingly popular. So here are our ideas so far...

Girls:
Marianne
Ariadne (dh favourite but I feel too close in sound to Iris)
Madeleine
Harriet (my favourite)
Phoebe (getting too popular?)
Isolde
Elinor
Isobel
Matilda (nn Tilly)

Boys:
Miles
Alistair
Henry
Hayden
Toby

Struggling so opinions and suggestions welcome,

thank you for your help.

How about

Eloise/ Eloisa
Audrey
Alice
