Wilhelm Weyermann and Gertrudt Seipmans marriage
I have a copy of marriage record from LDS:
Wilhelm Weyermanns Von Rheydt
Gertrudt Seipmans Von Sin(z)?
Date from LDS is March 15, 1716
Place Prussia, Rhineland, Krefeld,Evangelisch
After looking at maps, I found Rheydt not far from Dusseldorf. There is also a place called Sinz.
IGI shows other Weyermans and Seipmans in both areas.
