I have not looked at any of the Cass Co. death certificates myself. I have
several certificates from other places. Most, of the certificates that I have
show the place of burial on them. The Cass Co. web site has a great deal of
information on it, including an index of births, deaths and marriages. The
index was transcribed by volunteers and placed online to be available to all.
The index may not be as complete as we all would like, but it helps
considerably. You might want to check that index and see if you can find the
relatives there. A copy of the death certificate may lead you right to the
cemetery. If it doesn't have the cemetery listed, it may give you an idea
what area they died in. It's a good place to start to look for them.
