We already have [name]Edie[/name] and [name]Isaac[/name] and I have fallen in love with [name]Sibyl[/name] (and I am preferring this spelling as of now) as a potential sister. [name]Do[/name] you think the name matches with siblings or at least isn’t too different stylistically? What middle name would sound good with [name]Sibyl[/name]? I haven’t come up with a combo I love yet… Siblings middles are [name]Rose[/name] and [name]Edward[/name] and I don’t want anything ending in y/ie sound… suggestions and thoughts on potential sibset [name]Edie[/name], [name]Isaac[/name] and [name]Sibyl[/name]? Thanks in advance!
I have [name]Sybil[/name] / [name]Cybil[/name] on my list too and I’ve paired it up with [name]Janelle[/name].
[name]Sybil[/name] [name]Janelle[/name] is somewhat whimsical & pretty.
I would choose something classic to ground it and keep it a little closer to siblings’ names.
[name]Sibyl[/name] [name]Catherine[/name]
[name]Sibyl[/name] [name]Elizabeth[/name]
[name]Sibyl[/name] [name]Victoria[/name]
[name]Sibyl[/name] [name]Frances[/name]
[name]Sibyl[/name] [name]Beatrice[/name]
[name]Sibyl[/name] [name]Susannah[/name]
@ Albertamomabear - thanks for that suggestion, never thought about that combo though I am unsure if I like the double L-ending names together… Maybe [name]Sibyl[/name] [name]Jane[/name]?
@fairchild - thank you. I have [name]Catherine[/name], [name]Elizabeth[/name] and [name]Frances[/name] jotted down already. [name]Elizabeth[/name] is a family name on both sides though I’m not sure about the flow. I am really liking [name]Sybil[/name] [name]Frances[/name] and [name]Sybil[/name] [name]Victoria[/name] is a very pretty combo!
I have [name]Sybil[/name] [name]Kay[/name] on my list!
[name]Edie[/name], [name]Isaac[/name], and [name]Sybil[/name] are a really nice sibset. I like your combinations of [name]Sybil[/name] [name]Frances[/name] and [name]Sybil[/name] [name]Jane[/name] a lot. Some other possibilities:
[name]Sybil[/name] [name]Ann[/name]/[name]Anne[/name]
[name]Sybil[/name] [name]Claire[/name]
[name]Sybil[/name] [name]Jean[/name]
[name]Sybil[/name] [name]May[/name]/[name]Mae[/name]
[name]Sybil[/name] [name]Ruth[/name]
thanks daviesellu! I am also a big fan of [name]Mae[/name] and [name]Ann[/name] is a family name. I love the simplicity of [name]Annie[/name] as a name but as a middle sometimes [name]Ann[/name] sounds like a filler. Thank you for your ideas - I really really like [name]Sibyl[/name]/[name]Sybil[/name] [name]Claire[/name] 
I love your sibset. [name]Sibyl[/name]/[name]Sybil[/name] is a really nice name and I like both spellings.
[name]Sibyl[/name] [name]Clara[/name]

[name]Sibyl[/name] [name]Megan[/name]
[name]Sibyl[/name] [name]Rebecca[/name]
[name]Sibyl[/name] [name]Josephine[/name]
Honestly, I much prefer [name]Sylvie[/name] and possibly [name]Sybilla[/name] - but if you’re going with [name]Sybil[/name] (which isn’t terrible dont get me wrong)
[name]Sybil[/name] [name]Eleanor[/name]
[name]Sybil[/name] [name]Caroline[/name]
[name]Sybil[/name] [name]Jessamine[/name]
[name]Sybil[/name] [name]Katarina[/name]
[name]Sybil[/name] [name]Henrietta[/name]
[name]Sybil[/name] [name]Iris[/name]
[name]Sybil[/name] [name]Emmeline[/name]
[name]Sybil[/name] [name]Lenore[/name]
[name]Sybil[/name] [name]Adelaide[/name]
emelis- I do love [name]Sylvie[/name] too (and [name]Sophie[/name] even though it is more popular and I wouldn’t likely use it) but [name]Sibyl[/name] has really grown on me. [name]Sibyl[/name] [name]Eleanor[/name] is one I have considered (and it gives an E which is an initial in every other family members first or middle so that would be an added bonus even though I’m not looking for a name specifically for that reason) and also like [name]Sibyl[/name] [name]Emmeline[/name] (would you pronounce it [name]Emma[/name]-line or [name]Emma[/name]-leen? I think I like it as [name]Emma[/name]-line when paired with [name]Sybil[/name]/[name]Sibyl[/name])
castles- thank you for liking the sibset!! [name]Sibyl[/name] [name]Alexandra[/name] is a beautiful combo.
I usually same [name]Emma[/name]-line. And I agree that it sounds better with [name]Sybil[/name]. I really like the way it looks as well.
I adore [name]Sibyl[/name] (this is my favourite spelling too) and it sounds great with your set.
[name]Sibyl[/name] Esmé
[name]Sibyl[/name] [name]Elspeth[/name]
[name]Sibyl[/name] [name]Erin[/name]
[name]Sibyl[/name] [name]Eliza[/name] - I did like [name]Elizabeth[/name] but [name]Sibyl[/name] [name]Elizabeth[/name] “reads long” compared to [name]Sibyl[/name] [name]Eliza[/name], [name]IMO[/name].
I also really like names with the accent on the 2nd syllable, like [name]Marie[/name] (but [name]Marie[/name] is used-and-abused as a middle so I’m trying to think of others)
[name]Sibyl[/name] [name]Elise[/name]
[name]Sibyl[/name] [name]Joelle[/name]
[name]Sibyl[/name] [name]Raquel[/name]
[name]Sibyl[/name] [name]Chantal[/name]
[name]Sibyl[/name] [name]Irene[/name] (I like the image of an oracle of peace)
stripedsocks- Thank you for the thoughtful response! I too think [name]Sibyl[/name] [name]Eliza[/name] might be a better fit with my kids names. I agree with the accent on second syllable names and think they pair well with [name]Sibyl[/name]. [name]Rose[/name], my daughters middle name is named after her great grandma, whose sister is [name]Irene[/name]… so [name]Sibyl[/name] [name]Irene[/name] has a family connection too. I also like [name]Irena[/name]. [name]Do[/name] you think [name]Sibyl[/name] [name]Irena[/name] works? Funnily enough her initials would imitate her name - S.I.B. if I chose I for a middle name. I also am drawn to [name]Sibyl[/name] [name]Elise[/name] but like the 3 syllable middle name I think (though I am not going to chose a name based on this)
I really like [name]Sibyl[/name] [name]Elise[/name], [name]Sibyl[/name] [name]Irene[/name], and [name]Sibyl[/name] [name]Emmeline[/name]! Those are all very pretty.
Also, I have a friend who spells it [name]Sibylle[/name], just throwing that out there.
[name]Love[/name] [name]Sibyl[/name] too! [name]Sibyl[/name] [name]Emmaline[/name] is lovely if slightly L heavy. [name]Sibyl[/name] [name]Irena[/name] is gorgeous!
[name]Sibyl[/name] [name]Mary[/name] is a classic idea.
[name]Sibyl[/name] [name]Beatrice[/name]
[name]Sibyl[/name] [name]Phoebe[/name]
[name]Sibyl[/name] [name]Marian[/name]
[name]Sibyl[/name] [name]Frances[/name]
[name]Sibyl[/name] [name]Katherine[/name]
[name]Sibyl[/name] [name]Madeline[/name]
Anything appeal?
I adore [name]Sybil[/name] in all her many spelling variations! [name]Edie[/name], [name]Isaac[/name] and [name]Sybil[/name] sound utterly perfect to me. My first thought for a middle name is [name]Sybil[/name] [name]Iris[/name], which sounds divine, don’t you think?
I like [name]Sybil[/name] [name]Irena[/name]!
