It seems
Iris and
Majken are popular names for sisters, I've seen it before. Some years ago I would have named my daughters those names too, but now they're too popular for me.
Nellie and
Eleni seem too close, most of the same letters. And twins
Moa and
Nea, even worse since they may be identical.
Siri Christina - Just the other day I thought it would be cool if a little girl was called
Kristina, wonder when it's going to get back in style.
Adore the sibset
Svante and
Flora! And Tage is lovely too.
