Finland - oldest brother

Sweden - second oldest brother

Denmark - third oldest brother

Norway - middle brother

Iceland - third youngest brother - twin

Greenland - third youngest brother - twin

Faroe - second youngest sister

Åland - youngest sister

Ok so just note that in my books, Faroe and Åland are super young, so if their is war, they would not participate in it.

Also, I need help on this, who would the mother and/or father be?
