she is from Belgium. As you may know or not know Belgium is split up in the northern half ( Flanders) whose native tongue is Dutch ( in a nice way) and the southern half ( Wallony) speak French. So Dana Winner is definitely not Dutch and much as she likes performing in Holland would probably feel offended being called Dutch. If you take into account the Dutch speaking population of Belgium + the Netherlands we are talking roughly about 20 million people whose mother tongue is Dutch. You can imagine that internationally speaking one would not come very far with our language. If you watch her concert the link of which I gave you here you will notice that she sings immaculately in German, Spanish, French and Dutch and pretty darn good in English as well.
Thank you guys for your feedback by the way. I guess I got carried away somewhat because I think she is like a good wine.
Maturing and getting better and better with age. She is 51 now.

John
