Try writing to the Chippewa County Genealogical Society, 123 Allen Street, Chippewa Falls, WI 54729-2898. Please include a SASE.
They have various Cemetery Indexes and notebooks.Would be more productive than writing to the cemetery which probably doesn't have an office.Sometimes those prairie cemeteries are just out there doing their own thing all the windy day and night long.
By the way, why don't you list all the relatives you are looking for?That way, you might stir a cousin or two that may actually be able to go look for you!!
