Finnish male names

Unlike many other languages the following words in Finnish are used as male names:

  • Hope (Toivo)
  • Faith (Usko)
  • Darling (Armas)
  • Grace (Sulo, Kauno)
  • Precious (Aarre)
  • Enchantment (Tenho)
  • Happiness (Onni, Auvo)
  • May (Touko)

I wonder what this says about Finnish culture.
