Yes K., you did it the way the Dutch Naming Conventions prescribe, with one tiny thing: punctuation is never part of the first name, so "Claesdr." should be "Claesdr", without the period. "Claesdr" is a patronymic, meaning Claesdochter (Claesdaughter), so her father's first name would be Claes.
And by the way: the concept of middle name is unknown in the Netherlands, so it should never be used, and the radio button "no middle name" should be activated. Multiple given names are recorded in the proper first name field.
