I looked through all of the cemeteries at the Johnson County Genealogical Society's web page, http://user.htcomp.net/JCGS/cem.htm

Sometimes where a person was buried will be in their obituary or on their death certificate. There is a volunteer who will look up obits at www.gengathering.com
. You do need to create a user ID and password to enter this web site but access to the volunteer info is free. Successful Searching!
