It isn't set in stone that the boy has to have Frederik or Christan and for the girl Ingrid and Margrethe.
I'm hoping we don't see any reoccurring family names unless it's for a specific reason.
I think it is set in stone that the little prince is named "Frederik" with one of his name (likely not the first name, which is used on a daily basis, because that would be confusing).
But i think they will not use Christian as a middle name, because of their other son.
Ingrid or Margrethe might be used again, although it is used for Isabella. But just one of them, not both, because that is to much copying Isabella's name.
I take it for granted that they will use a traditional danish name as a middle name. They did so when using Ingrid and Valdemar. So Thyra, Dagmar,
Gertrud, Hedwig, Ingeborg, Frederikke, Ulrike, Louise, Mathilde might be used as a middle name.
I love the name Feodora, but it is to unusual for a first name. Might be middle name, but i think they will not consider Feodora at all.
So in the end they might use the following combinations - just my predictions
4 name in total:
- 1. name, because they might like it.
- one middle name will be traditional Danish
- one or two middle names will be the names of a relative
