[name_f]Rosalind[/name_f] is a different style to [name_f]Lily[/name_f] and [name_f]Holly[/name_f] and I would be surprised by it in the set, but I have met siblings like that before (think [name_f]Maisie[/name_f] and [name_f]Arabella[/name_f], [name_f]Emmy[/name_f] and Helena) so it’s not undoable and I don’t massively overthink it when I’ve met those sibs. I think it could work.
[name_f]Do[/name_f] I think [name_f]Ruby[/name_f] and [name_f]Poppy[/name_f] fit stylistically better? Sure, but I guess siblings aren’t always going to be referred to together
