I can't verify your grandfather's death date.I have been through all of the newspapers from that time period and didn't see anything.I tried to catch all of the probate records as well, but I'm sure that I have missed some of them.Reading microfilm can get difficult with the old newspapers.
I do have the following information:
Shultz (unnamed)27 Aug 1896(paper unknown, forgot to write it down :( )p. 8 bur. "saturday" res. Adams county, NEage:5 months parents:Mr. & Mrs. Shultz cause of death:dysentry
Shultz, JessieThe Minden News19 May 1898p. 8 sp. Maggie E. White md. 17 May 1898MInden, NE note: White from McCook, NE
I also found a reference to another Shultz / Schoultz from earlier:
