Looking for fresh ideas

Looking for classic/vintage but not overused names (isn't everyone). A little lyrical. Last name starts with S and is 3 syllables with a lot of hard consonants. Oldest is Leo. Would be great if middle names could be Jean/Elizabeth or John.

Girl names I like: Ruby, Ainsley, Phoebe, Penelope, Julia
And for boys: Malcolm, Gabriel, Julian, Grant, Caleb
