There are now 4 proposed parents for Geertje Aeltje Gerritz, SM/PROG on Geni - none of which have any sources.
Neither http://www.ballfamilyrecords.co.uk/olivier/I112.html nor http://www.e-family.co.za/ffy/g5/p5296.htm cite any parents.
I'm removing all the parents, pending Primary Sources being provided, and locking the relationships:
