I have recently started crushing on this name and can’t get it out of my head. But I can’t think of any good names for a brother or sister to [name]Heloise[/name].
Nothing feels like it works, help please!
Maybe…
Girls: [name]Aphra[/name], Soirse, [name]Adair[/name], [name]Genevieve[/name], Alarice, Bathilda, [name]Circe[/name], [name]Fiore[/name]
Boys: [name]Gregor[/name], [name]Anatole[/name], [name]Calix[/name], [name]Ansel[/name], [name]Mathias[/name], [name]Pascal[/name], Raziel
??
I love when I can just randomly brainstorm names! 
[name]Heloise[/name] and…
[name]Greta[/name], [name]Greer[/name], [name]Heidi[/name], [name]Eleanor[/name], [name]Danica[/name], [name]Marianne[/name], [name]Lynette[/name], [name]Annette[/name], [name]Matilda[/name]
[name]Ambrose[/name], [name]August[/name], [name]James[/name] nn [name]Jem[/name], [name]Barnabas[/name], [name]Oliver[/name], [name]Edwin[/name], [name]Scott[/name], [name]Otto[/name]
I would absolutely love [name]Heloise[/name] and [name]Sylvie[/name] as sisters! They are perfectly matched in my opinion, and they compliment each other so well. [name]Both[/name] have the traditional, sweet, French feel. Some other suggestions:
[name]Heloise[/name] & [name]Iris[/name]
[name]Heloise[/name] & [name]Adelaide[/name]
[name]Heloise[/name] & [name]Amelia[/name]
[name]Heloise[/name] & [name]Isabela[/name]
[name]Heloise[/name] & [name]Margaret/name
[name]Heloise[/name] & [name]Serena[/name]
[name]Heloise[/name] & [name]Olivine[/name]
[name]Heloise[/name] & [name]Lorelei[/name]
[name]Heloise[/name] & [name]Magdelene[/name]/a
For boys, I love [name]Heloise[/name] and [name]Phinneas[/name]; they are a little similar, but I think they really work amazingly together. And, some more suggestions:
[name]Heloise[/name] & [name]Willem[/name]
[name]Heloise[/name] & [name]Henry[/name]
[name]Heloise[/name] & [name]James[/name]
[name]Heloise[/name] & [name]Samuel[/name]
[name]Heloise[/name] & [name]Julius[/name]
[name]Heloise[/name] & [name]Thomas[/name]
[name]Heloise[/name] & [name]Augustine[/name]
[name]Heloise[/name] & [name]Atticus[/name]
[name]Heloise[/name] & [name]Fyodor[/name]
I’m loving [name]Olivine[/name], [name]Matilda[/name], [name]Circe[/name], and [name]Julius[/name]. I feel like they all have the right level of spunk that [name]Heloise[/name] does. While I really love some others, like [name]Eleanor[/name], somehow they sound too similar to me.
The suggestion of [name]Margaret[/name] actually got me thinking though, and I love [name]Marguerita[/name] with [name]Heloise[/name]! I also came up with a few more, tell me what you think, & keep the suggestions coming!
[name]Heloise[/name] & [name]Sabina[/name]
[name]Heloise[/name] & [name]Alasdair[/name]
[name]Heloise[/name] & [name]Leopold[/name]
[name]Heloise[/name] & [name]Tristan[/name]
[name]Heloise[/name] and…
[name]Adeline[/name]
[name]Genevieve[/name]
[name]Estelle[/name]
[name]Evette[/name]
[name]Lucille[/name]
[name]Henri[/name]
[name]Julien[/name]
[name]Blaise[/name]
[name]Remi[/name]
[name]Christophe[/name]
Oo, [name]Julien[/name] is great. Not sure if I like that sp, or [name]Julian[/name] more
[name]Blaise[/name] is another name I’ve recently come to like quite a bit, but I think it ends to closely to [name]Heloise[/name]…
Me again 
I love [name]Sabina[/name] ([name]Sabine[/name] works a little better though, imo), [name]Alasdair[/name] and [name]Leopold[/name] as siblings for [name]Heloise[/name]! I also think [name]Julien[/name] would be gorgeous. Another one which I think would work well is Th”ophile [tay-oh-feel], though not many are keen on it.
