Inmate at Cook home for the poor, Duluth 1942

I am searching for my Great great grandfather Rasmus Olai Hanson born in Davik Norway first of March 1856. He emigrated without his family and I have no reliable information about him except the Declaration of second february 1900 in New York. In the 1940 United States Federal Census from Duluth, St. Louis Minnesota there is an inmate at Cook home for the poore with the same name, nationality, and estimated birth year 1857. In Park Hille Semetry, Duluth, there is a grave in the name of Rasmus Hanson 1856-1942. In Minnesota Deaths 1887-2001 there is a Rasmus Hansen, Borne in Norway 1856 with correct fathers name and dead in Duluth 29. of May 1942. I feel i am close to conclude with that my Great great grandfather died in this poorhouse. Anyone who can help?
