Aimo

This name sounds a bit dorky and old fashioned to me, probably since the word has often been used (intentionally) in such ways around me. The Finnish name register shows that Aimo was most popular from the 20s to the 50s, which also explains the dated image I get.

Generous amount of what, exactly?

I like this name a lot. The final "A" gives it a zippy sort of feel, the kind of name for someone really spirited and energetic.
