Ingo is not popular anymore at all. It's very middle-aged. I'd think it very strange to see it on a baby, but these kinds of names are becoming popular again for some reason, so I guess it shouldn't be so surprising to see a little
Ingo. It reminds me of a fisherman with a long beard wearing rubber boots. Hmpf. I like
Joseph (if it's pronounced the English way, that is) but together with
Ingo it all seems too dated in my opinion.
