The original source on this profile was (2) The Rosenkrans family in Europe and America, which I expanded on and added more sources, but for those parents Willem is on the church record not Apollonia. Could they still be the same person?
Is there any proof that Apollonia exists at all? The NJGS says that she died young. http://njgsbc.org/files/BCFamilies/BCFam-Rosencrantz.pdf Maybe she's just an assumed child based on her maternal grandmother's name, Apollonia Barents?

According to the Brouwer Genealogy Database http://freepages.genealogy.rootsweb.ancestry.com/~brouwergenealogydata/p568.htm#i50991 she's mentioned in the article "Dr. Kenneth Scott, "The Vredenburg Family", New York Genealogical & Biographical Record Vol.95, pp.79-86 (1964): p.85. Hereinafter cited as "NYG&BR 95:79-86." ?
There is a marriage record on that profile for an Apollonia Rosencranz (Roosekrans), but it doesn't mention parents.
Oh, her baptism date is recorded wrong somewhere. She's here on 31 Oct 1697 https://archive.org/stream/baptismalmarriag00king#page/50/mode/2up
