If you and DH like two-syllable names like Emma and Pippa, what about names such as :
Anna, Anya, Clara, Stella, Frances, Sarah, Zara, Susan, Juno, Helen, Lorna, Clea/Cleo, Thea, Leah, Julie, Sylvie, Hebe (a shrub and a goddess!), Cora, Tessa, Edith...
These questions might just perhaps help narrow down the possibilities:
Would you want - or NOT want:
- name starting with 'D', eg Daisy and Dora?
- very long name (unbalanced??) eg Daisy and Evangelina?
- name ending in an 'ee', 'ie' sound or 'y' spelling, eg 'Daisy and Molly' or 'Daisy and Ruby, Elsie, Sally, Sophy ?
- name with matching 'a' sound, for example, 'Daisy and Mabel', or 'Daisy and Ailsa', 'Daisy and May'?
6.flower name , but with a different sound: eg Daisy and Rose, Daisy and Lilac, Daisy and Fern ...
- Flower name from a different language or with different origins: eg Rhoda (= Rose), Laura (=laurel) etc
- A different nature name (bird, tree...), eg Linnet, Rowan, Saffron, Holly, Willow
- Since Daisy is short for Margaret, you'd presumably want to avoid Maggie, Margot, Pearl, Greta etc
