What a beautiful list of names! I love nordic names (I am Norwegian myself). My favourites from your list are:
Atelia
Valentina Tilli (although I would prefer
Tilly, but still a sweet name)
Augustin Gideon Nicolaus (always loved this name)
Natanael (such a beautiful name, I like it better than
Nathaniel)
I’ve discovered some old, Nordic names myself lately. And some
German. I have started researching my heritage lately. And the most interesting names I found are (I am not sure if all the spellings are correct):
Margit Konstance (f)
Emil Gunerius (m)
Mikal (m)
Lina Alette (f)
Alette
Sophie (f)
Matea (f)
Reinhold Helmut Gustav (m)
Friderika
Emilia Rozalia (f)
Finding the names is one of my favourite things while looking for my heritage. Maybe I’ll use some very old names for my own children in the future.
