Some comments:
Nikolas Verneri - Nice to see a
NikolasKristoffer Edwin Taavetti, brother
Oliver - Now that's a mouthful! Is
Taavetti making a comeback (at least as middle name)...?
Valtti
Juhani - Valtti is interesting! I don't know if I like it or not.
Juhani is a bit blah.
Maria Aleksandra - This is one of my favourite combos! And
Aleksandra spelled with ks instead of x!! I love these people!!!
Kaisla
Lilian, sister
Alisa (
Laura and
Lauri) - Don't care for the kids' names, but I just have to note that I know a couple called
Laura and
Lauri too, lol.
Silja Sofia -
Silja is lovely.
Ruska
Adelia Ilmatar, siblings
Lumi and Touko - Uh oh. First, I like Ruska - for a boy. I checked the Name service and it appears to be mostly used on girls though. Hmm. I like
Adelia and
Ilmatar.
Ronja Saaga
Eleonoora - I was just thinking about
Eleonoora the other day, and whether it's usable or not. It's so long and a bit clunky. It does work as a middle name at least.
Leonie Ingrid Alexandra, sister
Emelie Sophia Christina (
Hanna and
Valtteri) - Surname... Möttönen?
Siri Ingrid Olivia - I like this combo!
Siri Ingrid is so full of "hard" sounds, and
Olivia softens it beautifully.
I guess you live in an area with a lot of Swedish-speaking population? :)
