Sorry to burst your bubble - but there does NOT appear to be any evidence that Annetje was a Terhune.
Below are baptisms associated with this couple - none of the witnesses can be tied to the Terhune family.At one time I also thought her to be a Terhune but I would suggest you look among the Koning, Van Vleck and/or Borgers families for her identity.
