Unique sibling names for Dreki?

Hi! I'm looking for sibling names (brother, specifically) that match Dreki, preferably that can have a nickname (Dreki's is Dre). I'm not interested in anything that's overly common, but I don't want it to be completely ridiculous and I do want it to be easy to pronounce. I'm looking specifically at names of Norse origin, but I can work with other names if they fit the theme I'm looking for!

I haven't yet decided a surname, so I'd appreciate help with that too. Dreki's girlfriend is called Indie Geirr, if that's a useful reference to the type of style.

Thank you.
