My step father is a Ugelstad (I took his last name). I'm not 100% sure, but in my tree I have them listed as follows.
Donald Lee Ugelstad (my step father)
Melvin C. Ugelstad (1896, Barlow, ND - 1966, Tacoma, WA)
Jens E. Ugelstad (1863, Norway - 1957, Fargo, ND)
Elias Erickson Ugelstad (?, Norway - 1878, Norway)
To be honest, I can't remember where I got the information from so I'm not 100% positive.
I would take any information or pictures you may have. My family would love them.
