[name]Edward[/name], [name]Adelaide[/name], [name]Isaac[/name] and …
[name]Alice[/name] - speaking from experience (this name is well within the top 100 here in [name]Britain[/name]), once it’s in use again it will rise very quickly in popularity. According to Nameberry :
“In the past year alone, it’s jumped from #327 to #258!”
[name]Philomena[/name] - I do like the unusual, very vintage feel of this name, but I’m afraid I find it less pretty than the lovely [name]Adelaide[/name], and I worry that she would, too.
[name]Arabella[/name] - I think this could work as it has the same vintage feel as [name]Adelaide[/name], but they are both A names - does that bother you?
[name]Elizabeth[/name] - definitely not boring with all of those possible nicknames! She would share an initial with [name]Edward[/name], but I think [name]Elizabeth[/name] nn [name]Eliza[/name]/[name]Betty[/name] would fit perfectly into your family.
[name]Molly[/name] - I do find her looking ever so slightly nickname-y next to your other children’s names, but she would still be a sweet, good, vintage choice.
[name]Leona[/name] - I don’t feel like this one has the same vintage quality as your other children’s names.
[name]Winifred[/name] - a fun vintage choice, but like [name]Philomena[/name], it feels slightly off to me with your other children’s names. [name]Edward[/name], [name]Adelaide[/name] and [name]Isaac[/name] are vintage in a very accessible way, whereas [name]Philomena[/name] and [name]Winifred[/name] are very, very vintage.
[name]Madeleine[/name] - or [name]Madelyn[/name]. Ugh … I’m afraid that and [name]Madison[/name] have ruined this once lovely name for me.
[name]Annabelle[/name] - I personally think this one is too popular next to your other children’s names (I also must say that I prefer the spelling of [name]Annabel[/name] …).
[name]Thomasina[/name] - see [name]Philomena[/name] and [name]Winifred[/name].
[name]Nora[/name] - a bit nicknamey, yes, but it doesn’t feel drastically so next to your other children’s names, and it definitely has the same feel as they do. It could be a nn for [name]Eleanor[/name], [name]Eleanora[/name], [name]Leonor[/name], [name]Leonora[/name], [name]Honorine[/name], [name]Honora[/name] or [name]Annora[/name].
My favourite of your options is [name]Nora[/name].
My suggestion would be [name]Beatrice[/name]/x or [name]Cecily[/name], both of which I think would be perfect in your family. I’m also wondering about an O or a U name, as you already have the other vowels and that might be a subtle, sweet theme …

[name]Olive[/name] (or [name]Olivette[/name])
[name]Olympia[/name]

[name]Ophelia[/name]
[name]Oriana[/name]
[name]Orinthia[/name]
Ornella
[name]Ottilie[/name] (or [name]Ottoline[/name]).

Good luck! [name]Auburn[/name]
