I don't like matchy-rhymey sibsets in reality. It's cute for a story, but in real life I think children should be considered individuals. Not collections of a set. Then again, there are some exceptions that I like to my own rule (floral middle names in a set, for instance) so maybe I'm just full of it :P
I think
Liberty and
Charity feel 80s-90s dated. I like
Serenity. Not a big fan of
Verity.
If I had to adjust the names (assuming you want them to be words) I'd choose:
1.
Serenity2.
Felicity3. Levity
4. Divinity
I tried to pick names with feelings I'd want them to experience, rather than exemplify. I only like
Serenity and
Felicity, though!
