Dag Hammarskjöld - I know, even though I couldn't remember why he was famous, because I live very near a street named after him (in Copenhagen, though he was Swedish).
Dag is not a name in common use in Danish, though it may well have been in the past. I do think of more as a Swedish/Norwegian and maybe Icelandic name. It does mean day in Danish and if I'm not mistaken Swedish and Norwegian as well.

I think you do have a third Dag but I can't remember where. A minor character.

Yes, you are correct, dags are the bits of wool and poo that mat into dreadlocks on the back of a sheep and also in Australia you call someone a 'dag' if they dress poorly and / or are unfashionable in dress or speech. Although you can also affectionately refer to someone as 'a bit of a dag'.

Here I was thinking it was short for Dagwood & Blondie...

I believe that the Australian /nz term for those shitty dreadlocks actually comes from the much older term dagging meaning those self fringed or scalloped edges on medieval clothing. You can see how a sheep bum resembles the fashion detail (less)

The Amish need to learn that slang word. They call the same sheeply trait "aarschglob." Much longer and less euphonious...I suppose that could almost be onomatopoeia.

In Ethan of Athos, early in the book, there is a minor character, a farmer on Athos, also called Dag.
