guild

I have a relative that was a Paper Maker Master.
Wilhelm Wimpelberg: He comes to Meidereich, Duisburg, Duisburburg, Nordrhein-Westfalen, Deutschland in 1770-80 with that occupation.
It is believed he came from Kettwig Essen.
The question is is there a register for Guild members or a listing of Mastercraftmen?
Germany wide or just in different areas.
