I don't know many either. Off the top of my head I love:
Anouk,
Femke,
Aloisia,
Saskia,
Nicolaas,
Hieronymus (or is that Latin?),
Bram,
Gerrit. Schyler is also Dutch, but it's been butchered so much here in the U.S. spelling and gender-wise that I've given up on it.
Have you gone through the Dutch names here at behindthename.com? If you go to the home page you'll see a section that lists names by origin. If Dutch names aren't on the home page, just click the link to get many more lists. I'll go there now and see what I think would be useable.
ETA: OK. So that was fun. There are so many names that I love over there in the Dutch names section. But many are exactly the same as the English form. So I've left those off. Here are some (hopefully obvious) Dutch names that are useable and fun:
Adelheid /
Alida /
ElkeAmalia (nn
Molly?)
AnnekeAnnelieseBrigitta (hard "g" sound)
CarolaEvelienFilomenaGilbertaGisela (hard "g" sound)
