  state.

  therein a lien is claimed, and the interest of the owner as far as known
  to the lienor.
    3. The name of the person by whom the lienor was employed, or to  whom
  he  furnished  or  is  to  furnish  materials;  or,  if  the lienor is a
  contractor or subcontractor, the person with whom the contract was made.
