You could start with www.genlias.nl to find the marriage of Gijsbert (don't use Gysbert ) and Aartje. You will be suprised because Gijsbert was married before and I think that the mother of your grandfather Evert isn't Aartje but Cornelia Peelen.
Do you know in witch place Evert is born ?
A lot of records are online. We use Familysearch but to know where to look we first go to www.genver.nl
