Ahhh this was hard. I adore your UC Rory!
I think my favourite set is Maxine Marigold, Beatrix Astraea, Winifred Lunaria & Caspian Apollo. Together they are dreamy, maximalist and whimsically vintage! Personally I love when a sibset has a pattern, and in this set it’s strong first names, luminous middles and snappy nicknames. They are all perfectly cohesive (especially love how Max and Bee both have an X) without being matchy matchy. 
My honourable mention is Agnes Hollyhock, Dolores Lavender and Henry Oleander. I love to see Dolores (and Dolly 
) especially with her charmingly vintage siblings’ names! Hollyhock is so cool too. 
What are some nicknames for Edith that aren’t Edie?
