Could you help me? I love the names [name]Sojourner[/name], [name]Elizabeth[/name] & [name]Penelope[/name]-but I can’t come with any sibling names that meet the criteria: [name]Long[/name]-ish, Serious with a nn that’s cute, slightly (or over-the-top) quirky, more than three syllables, preferably not ending in A, but if you have a couple, by all means, tell me!
[name]Clementine[/name] (might not be as serious as you’re looking for, but I think it goes beautifully with the three names you already picked out - [name]Clem[/name] or [name]Cleo[/name] are cute nicknames!)
[name]Magdalen[/name]
[name]Augustine[/name]
[name]Adrienne[/name]
[name]Ottilie[/name]
[name]Adelaide[/name]
[name]Apolline[/name]
[name]Bernadette[/name]
[name]Damaris[/name]
Firenze
[name]Genevieve[/name]
[name]Gwendolyn[/name]
[name]Orabelle[/name]
[name]Opaline[/name]
Some A names to consider if you’d like:
[name]Agnella[/name]
[name]Ambrosia[/name]
[name]Aminta[/name]
[name]Maxima[/name]
[name]Mathilda[/name]
[name]Calista[/name]/[name]Calixta[/name]
[name]Cosima[/name]
[name]Aurora[/name]
[name]Odetta[/name]
[name]Althea[/name]
Hopefully this helps you out! My favorites with your set would have to be [name]Clementine[/name], [name]Gwendolyn[/name], [name]Opaline[/name], and [name]Mathilda[/name]. I think they are all uncommon choices that are elegant and serious with cute nicknames - [name]Cleo[/name]/[name]Clem[/name], [name]Gwen[/name], [name]Opal[/name], and [name]Tilly[/name]. Good luck!
