Genealogy / Is Wajman or Wayman a Polish name? [15]

Does anyone know if Wajman or Wayman are common polish names? I think that they are just variations on each other. I am told that they are from Poland but were Germans. They came to the US in 1885. I am having a very hard time finding where in Poland they would have been from. If anyone knows anything about these last names, I would really appreciate your help.
