No, the spelling is correct, Natasja is a member of the third branche of the Aholt-family. From 1723 to 1860 her family lived as Ahout in the Dutch capital of Amsterdam, and nowadays the descendants are living in the province of North-Brabant. Of course, just like cheese and windmills are cows a trademark of Holland. My distant cousin Natasja once painted these silly beasts, but not only them. She shows her artistic work here on her website, and also here on this slideshow.
