The Hempel funeral home has been taken over by:
Ruminski Funeral Home
167 Wautoma Road
Redgranite, WI. 54970
They would probably have access to records from the Hempel era.
Also, to clarify, Wautoma is a separate city from Lohrville although both are in Waushara County. Neither has a hospital. Wautoma's population is about 2,000 but Lohrville has only a few hundred.
