Thank you for your reply. I hadn't considered the "aa" in the van de Waatering, but the mention of Schevening does seem to be correct.
With your date, I can look further. I find that the father Simon is also from Berkel en Roderijs, even the brother of the Pieter mentioned in my first post.
I find the index of her baptism, using the name "van Kempen" in the index for Scheveningen (see attached scan), which mentions the father as "Simon van de Wetering". There are two sisters and a brother baptised in the same period.
This looks good, thanks for the tips!
