I am looking for more information on Soren (poss. Alfred) Larsen and Lelia Laurine Larsen and their parents.

What I do have is this:

Soren Larsen, b. 7 Mar 1900, Copenhagen, Denmark
d. May 1985, Denver, Colorado
Son of Jens Christen and Mary Larsen

He married

Lelia Laurine Larsen, b. 23 Dec 1896, Vermillion County, Illinois
d. Dec 1975, Denver Colorado
Daughter of Jens Peter Larsen and Maren Hansen

I want to know when and on what ship did Soren immigrate to the United States? When did they get married and where? Who are their children? I only know of one.

Any help would be appreciated.
