Thank you for the reply.
Land description from GLO website: Aliquot Parts-N1/2SE; Sec/Block-15; Twp-31N; Range-12W. I do not have a map which defines that location.
Looking at 1880 through 1920 Censuses, Dunn Co. (WIGenWeb) and UW-Stout websites, I did not find mention of Halvor G. WIGEN.
I hope someone with knowledge of the man and his family will provide answers.
