I am looking for any and all information on my great grandparents who came over from Denmark in 1904. Here's what I know:

Their names were Hans Ludvig Nielsen (born March 13, 1873/died in Nebraska - probably Plainview/Pierce County about 1963) and his first wife Hansine Kristine Nielsen -
maiden name Mortensen (born about 1871/died about 1921 in Plainview/Pierce County, NE). Both, I am told, are buried in a place called "Danish Cemetery" in Copenhagen, NE.

When they immigrated to America they brought their four children -

Jens Christian Robert Nielsen (born about 1895)

Rose Marie Nielsen (born about 1898)

Ludvig (Louie) Nielsen (born about 1900)

Johannes (John) Nielsen (born about 1902)

They had at least three more children, that I know of, who were born in Nebraska -

Esther Nielsen (born 11 Feb 1905-19 Nov 1966)

Lila Nielsen (born Oct 13 - no other info)

Freddy Nielsen (died as a child).


On their trip to America they were traveling in the company of a Karl Vilhelm Mortensen (born about 1878), who might be a relative of Hansine's - a brother?

Hans and Hansine owned a farm in Plainview, NE on RFD 1. Hansine died some time between 1918 and 1923. Hans remarried after her death. His second wife's name was Myrtle Eunice Barrett (maiden Crowshaw).

I would like to learn the names of Hans' and Hansine's parents, or anything that might help me get to this information. Please help.
