Firstly congratulations
You’ve got a great list no wonder your struggling too narrow it down!
Primrose [name_f]Beatrix[/name_f] ~ [name_f]Primrose[/name_f] is of course stunning and she sounds really spunky with [name_f]Beatrix[/name_f]. [name_f]Primrose[/name_f] feels unexpected with [name_m]Theodore[/name_m] & [name_f]Isobel[/name_f] but works.
Primrose [name_f]Clara[/name_f] ~ I love both [name_f]Primrose[/name_f] & [name_f]Clara[/name_f]. [name_f]Clara[/name_f] is actually becoming a favourite of mine teamed with [name_f]Primrose[/name_f] the name sounds whimsical and elegant it’s so pretty.
Primrose [name_u]Wren[/name_u] ~ it’s a lovely name but prefer [name_f]Primrose[/name_f] [name_f]Beatrix[/name_f] & [name_f]Primrose[/name_f] [name_f]Clara[/name_f].
My favourite [name_f]Primrose[/name_f] [name_f]Clara[/name_f]
Calista [name_f]Pearl[/name_f] ~ this is elegant I love [name_f]Pearl[/name_f] and [name_f]Calista[/name_f] is sweet. I think [name_f]Callie[/name_f] for nickname is more attractive visually. [name_f]Calista[/name_f] I feel sounds very different with [name_m]Theodore[/name_m] & [name_f]Isobel[/name_f].
Calista [name_u]Wren[/name_u] ~ a spunky little name with a great sound.
Calista [name_f]Bloom[/name_f] ~ [name_f]Bloom[/name_f] is a gorgeous outdoorsy name feels delicate and sweet. I like [name_f]Calista[/name_f] with [name_f]Bloom[/name_f].
Calista [name_f]Rose[/name_f] ~ [name_f]Rose[/name_f] feels very expected and almost redundant. I love [name_f]Rose[/name_f] but I think I would prefer [name_f]Rose[/name_f] [name_f]Calista[/name_f].
My favourite is [name_f]Calista[/name_f] [name_f]Pearl[/name_f]
Delilah [name_f]Iris[/name_f] ~ this is a sweet name I like [name_f]Iris[/name_f] a lot and I think she sounds great with [name_f]Delilah[/name_f]
Delilah [name_f]Blossom[/name_f] ~ even though [name_f]Blossom[/name_f] is pretty it feels a bit too sugary with [name_f]Delilah[/name_f]
My favourite is [name_f]Delilah[/name_f] [name_f]Iris[/name_f]
Rosalind [name_f]Pearl[/name_f] ~ [name_f]Rosalind[/name_f] is charming and stylistically works well with [name_m]Theodore[/name_m] & [name_f]Isobel[/name_f]. I think [name_f]Pearl[/name_f] is so pretty with [name_f]Rosalind[/name_f].
Rosalind [name_f]Margot[/name_f] ~ [name_f]Rosalind[/name_f] is lovely and sounds great with [name_f]Margot[/name_f].
Rosalind [name_f]Violet[/name_f] ~ I absolutely love this such a gorgeous vintage name really love [name_f]Rosalind[/name_f] with [name_f]Violet[/name_f].
Hard one between [name_f]Rosalind[/name_f] [name_f]Pearl[/name_f] & [name_f]Rosalind[/name_f] [name_f]Violet[/name_f] but my favourite is [name_f]Rosalind[/name_f] [name_f]Violet[/name_f].
So I would narrow your list down too
[name_f]Primrose[/name_f] [name_f]Clara[/name_f]
[name_f]Delilah[/name_f] [name_f]Iris[/name_f]
[name_f]Rosalind[/name_f] [name_f]Pearl[/name_f]
