Any especially fab or perhaps unusual Dutch or Flemish boys names

[user1485182339]

Which might work well in the UK too? Feel free to throw in some girls' names, but mainly looking for boys' or gender neutral as our girls' list is reasonably populated already.
I guess there are mostly English equivalents, but I'd like to take stock of the Dutch/Flemish versions as my mind is pretty darn blank these days. TIA.

Local to us I know boys/men called
Jann
Thilo
Torbjorn
Mårten
Dirk
(None are Dutch, they are all German or Scandinavian).

For all of them, I heard the name before I ever saw it written, therefore I think I hadn't anglicised the pronunciation in my head. I could imagine problems at school, where staff would see the name written first.

Jort would be a disaster! I'm glad you married him.
Pipijn is a nice suggestion, but I keep thinking about a book a read as a child. No idea what anymore?
I've looked through all those online lists and I'm still stumped.

I knew a Dutch Saskia

Nils

Ernst
Willem
Daan

I love Pepijn.

I really love Kees (pronounced case)
