Annie - not keen as a standalone but really like Annabel, Anna, Anika etc
Mathilda - love it but wouldn't use the h in the spelling
Esther - like it. Unusual now too, I only know one under 7
Jocelyn - has really grown on me recently. I've never met a child with this name but think it's both pretty and feisty.
Evelyn - quite like it but not so keen on Evie which seems inevitable
Ottilie - not keen.
Eliza - not keen
Violet - quite like it
Audrey - really dislike it. Can't get past seeing it as an old lady name and thing it has an ugly sound.
