Hmm.... This is a confusing situation. There are conflicting accounts of the genealogy that seem to be based only on unsourced family trees.
I see that Gerrit Wyckoff listed a daughter Maryke in his will. His profile is connected to a profile for a daughter Marretje (same name as Maryke, Marritje, Marytje, etc.) at https://www.wikitree.com/wiki/Wyckoff-1126 (but I think the birth date of 1688 is too early, based on the name order in the will). That profile (sourced to a Geni family tree) shows her as married to Roelof Janse Terhune (but not connected to him).
Then we have the profile for Marritje that you asked to connect. It is unsourced and it has different parents, and it is connected to a different husband. Your source for the parents of Marritje seems to be an unsourced Ancestry Family Tree (not a reliable source).
It is unlikely that this confusion can be sorted out until we have some better sources....
