Who was J Fred Niehaus

For a long time, I have been curious about this person. He married my great aunt, Emma CUMMINS. He was b 1872- d 1938. He and Emma are buried in Dunn Hill Station Cem. in Sullivan, IL. Emma was b 1872- d 1936. They had no children, that I am aware of. I have no clue where he and his family are from.
