One last bit of information that I found. The Danish Cemetery used to be located in the SW part of Copenhagen, NE. Copenhagen is now a ghost town. Here is a link to the description: http://www.ghosttowns.com/states/ne/copenhagen.html . This is probably why the location of the cemetery is off in other records. The details given on this page list 862nd Rd and 531 Ave, instead of 862nd Rd and 530 Ave (as listed on the Find A Grave map).

Glad I could help :)
