With sister [name_f]Alice[/name_f] [name_f]Leonora[/name_f] (and potential brothers [name_u]Wesley[/name_u] and Paul), my favorites from your first name options would be [name_f]Emilia[/name_f], [name_f]Eva[/name_f], [name_f]Felicia[/name_f], [name_f]Lilia[/name_f], [name_f]Nessa[/name_f], [name_f]Talia[/name_f] / [name_f]Tahlia[/name_f], and [name_f]Violet[/name_f]. No votes would go to [name_f]Hannah[/name_f] (a bit plain next to [name_f]Alice[/name_f], which manages to be fey, soft, and precocious all at once), [name_u]Marie[/name_u] (always feels like a “filler” name to me), [name_f]Nyla[/name_f] (feels very modern next to the enduring classics that make up the rest of the sibset), [name_u]Piper[/name_u] (feels too unisex as a sister for [name_f]Alice[/name_f] and also has the modern / trendy vibe), and [name_f]Vanessa[/name_f] (feels very dated to me, and you’re considering [name_f]Nessa[/name_f] which I find much fresher).
For combo suggestions, I avoided pairing names that end in vowels with middles that begin with vowels for better flow, which is why [name_f]Siri[/name_f] and [name_f]Marianne[/name_f] show up more than [name_u]Anne[/name_u]. [name_f]Iris[/name_f] is actually my favorite of your middle options, but I didn’t think the flow worked with names ending in -a, and I thought [name_f]Violet[/name_f] [name_f]Iris[/name_f] might be too much, as they’re both purple flowers.
[name_f]Emilia[/name_f] [name_f]Siri[/name_f]
[name_f]Eva[/name_f] [name_f]Marianne[/name_f]
[name_f]Felicia[/name_f] [name_f]Marianne[/name_f]
[name_f]Lilia[/name_f] [name_f]Siri[/name_f]
[name_f]Nessa[/name_f] [name_f]Marianne[/name_f]
[name_f]Talia[/name_f] [name_f]Siri[/name_f] / [name_f]Tahlia[/name_f] [name_f]Siri[/name_f]
[name_f]Violet[/name_f] [name_u]Anne[/name_u]
I think [name_f]Nessa[/name_f] works beautifully as a standalone name, and is one of my favorite options from your list as a sister for [name_f]Alice[/name_f]. They both have a storybook vibe, and they’re both very sweet, demure-sounding names, but they each have a character namesake that gives them more of an edge under the softness. (For reference, I feel the same way about [name_f]Talia[/name_f] and Violet.)
Bonus suggestions for first names:
[name_f]Lucy[/name_f] - I think she fits the vibe and aesthetic of [name_f]Alice[/name_f] perfectly. If you don’t care for [name_f]Lucy[/name_f] as a standalone name, [name_f]Lucia[/name_f], [name_f]Luciana[/name_f], [name_f]Lucienne[/name_f], [name_f]Lucille[/name_f], and [name_f]Lucette[/name_f] are all potential long-form options. [name_f]Alice[/name_f] [name_f]Leonora[/name_f] and [name_f]Lucy[/name_f] [name_f]Marianne[/name_f] or [name_f]Lucienne[/name_f] [name_f]Iris[/name_f] would be lovely sisters.
[name_f]Juliet[/name_f] - Like [name_f]Alice[/name_f], she’s whimsical, romantic, and classic without feeling plain. [name_f]Alice[/name_f] [name_f]Leonora[/name_f] and [name_f]Juliet[/name_f] [name_f]Iris[/name_f] are beautiful together.
[name_f]Charlotte[/name_f] - A soft, gentle, underrated classic. I think a sibset of [name_f]Alice[/name_f], [name_f]Charlotte[/name_f], [name_u]Wesley[/name_u], and [name_m]Paul[/name_m] is just beautiful. [name_f]Charlotte[/name_f] [name_u]Anne[/name_u], [name_f]Charlotte[/name_f] [name_f]Iris[/name_f], or [name_f]Charlotte[/name_f] [name_f]Marianne[/name_f] would all pair well with [name_f]Alice[/name_f] [name_f]Leonora[/name_f].
I also absolutely ADORE the idea of [name_f]Clara[/name_f] with your sibset. It’s too bad about the dog!
Bonus suggestions for middles:
[name_f]Annemarie[/name_f] - Since you have both [name_u]Anne[/name_u] and [name_f]Marianne[/name_f] on your list, I thought you might like [name_f]Annemarie[/name_f]. I feel like she’s a little more unexpected and less dated than [name_f]Marianne[/name_f], while still containing those honor names. I think a sibset of [name_f]Alice[/name_f] [name_f]Leonora[/name_f] and [name_f]Violet[/name_f] [name_f]Annemarie[/name_f] would be beautiful!
For these next three, I wanted to find some alternative ways to honor the [name_f]Siri[/name_f] in your life without having to use the name itself since it’s so linked to the [name_f]Apple[/name_f] products. The name [name_f]Siri[/name_f] is a diminutive of [name_f]Sigrid[/name_f], which means “fair victory.” [name_f]Sigrid[/name_f] didn’t really seem to be your style, so I searched for names meaning “fair” and/or “victory” to see if there were any options you might like and found three potentials:
[name_f]Colette[/name_f] - A [name_u]French[/name_u] name meaning “people of victory” and a variation of both [name_f]Nicole[/name_f] and [name_m]Nicholas[/name_m]. I think [name_f]Emilia[/name_f] [name_f]Colette[/name_f], [name_f]Eva[/name_f] [name_f]Colette[/name_f], and [name_f]Lilia[/name_f] [name_f]Colette[/name_f] are all beautiful options for [name_f]Alice[/name_f] Leonora’s sister.
[name_f]Gwen[/name_f] - A Welsh name meaning “white; fair; blessed.” If you don’t care for [name_f]Gwen[/name_f] as a standalone name, there are quite a few long-form options - [name_f]Gwendolyn[/name_f], [name_f]Gwyneira[/name_f], [name_f]Gwyneth[/name_f], even [name_f]Guinevere[/name_f]. [name_f]Emilia[/name_f] [name_f]Gwyneth[/name_f], [name_f]Eva[/name_f] [name_f]Gwendolyn[/name_f], or [name_f]Lilia[/name_f] [name_f]Guinevere[/name_f] are all lovely paired with [name_f]Alice[/name_f] [name_f]Leonora[/name_f], though admittedly some variants are a little more uncommon and less classic.
[name_f]Victoria[/name_f] - A beautiful classic name meaning “victory.” [name_f]Nessa[/name_f] [name_f]Victoria[/name_f] and [name_u]Marie[/name_u] [name_f]Victoria[/name_f] have the best flow, but [name_f]Lilia[/name_f] Victora and [name_f]Emilia[/name_f] [name_f]Victoria[/name_f] would also be good options. [name_f]Victoria[/name_f] could also work in the first name slot, allowing you to use a second honor name as a middle. [name_f]Alice[/name_f] [name_f]Leonora[/name_f] and [name_f]Victoria[/name_f] [name_u]Anne[/name_u] would be lovely together.
I hope this is helpful and not too overwhelming, even though I didn’t stay perfectly within the suggestion limits!
