Just in case others find this searching for his burial record as I am also.
I've located a state census for 1885 that includes L D Hoisington and wife so he had to have died between 1885 and when she appears on census next in 1900 in Wyoming, Otoe, Nebraska. I saw on a hoisington genealogy site kept by Harriet Jensen that He and family were listed in Nebraska as follows below, but I haven't been able to locate it myself.
"Listed in 1885/1886 Gazeteer for Cass Co. NE
Hassington, F. J., Union
Hassington, John, Union
Hassington, L. D., Union
Hassington, M., Union "
So that's all we know so far. I've inquired with no luck of several regional historical societies including the links others have offered above with no luck. He can't have simply disappeared, so some record somewhere exists. Just a matter of finding it.
