I have come accross Catharin's Cornelisz Baptism records, and it states her father was Evertsz Cornelisz and mother Maria Syn Siegertz. It looks like an 'S" in Syn, but perhaps that stands for another letter. Not sure. Date of baptism 2 July 1673.

I cannot copy and put under her Sources on Geni.
Name on FamilySearch is:
Catharina Evertsz Cornelis van der Zee
ID No. 9XGN-C7B
The "Evertsz" part of Catharina's surname suggests that she was the daughter of Evert. The first baptism to take place on or after 1 July 1673 (the arrival date of the ship "Europa") at Cape Town for a child with the name Catharina (or variants thereof) happens to have been the following day. The parents were given as Evert Cornelisz and Maria Syn Siegertz (on baptism records)
Just not sure her parents d.o.b. are correct though. Perhaps someone can check up on this.
