John:

You're correct about Peter and Verena as parents of Ulrich. However, I show Peter's birth as February 4, 1621. That being said, you can get this and much more through the Schurch Family Association of North America website. Justin Houser has much information and is more than pleased to reply. Our association is quite active and if you are not aware of it, I suggest you visit and join. I do the Newsletter.
