Looking for Thorlief Diesen

Searching for information about my mother's cousin, Thorlief Diesen. He was born 1 May 1893 in Buskerud County, Frogner in Lier. His father was Ole marius Pedersen (Sjaesmo), mother was Indiana Amundson. Thorlief and his parents emigrated to USA in 1910 and lived in Northwood, North Dakota for a while, and in Tioga, North Dakota. The family lost track of Thorlief completely in 1930. Does he have descendants? in Norway? or in USA?
