I do like Efia and Effia and agree about
Pihla. Efia could work as a first name, it isn't dissimilar to
Sofia.
And I like:
Senja Irene Vanessa - Beautiful, flows like water
Hertta - so cute, sounds like herttainen
Iiris Armi
Elisabet
Amos Armand Ilo
Klaus Julius - very satisfying combination of letters
Sulo - same as Hertta.
Sulo and Hertta as siblings, ah, or
Onni and Ilo. Penni is adorable.
