Yes, it's Polk County, Wisconsin. My grandfather was born in Minneapolis the sixth child of Thekla and Dan/iel Carlstrom. Thekla died shortly after his birth. Daniel Sr. remarried and moved to Montana, leaving Daniel Jr. to be raised by his older sister Ester Gustafson. In 1936 he married my grandmother Doris Louise Hale Burdette in Polk County, Wisconsin. My mother was born in 1942, in St. Croix Falls, Wisconsin.
I have wondered before if Daniel Sr. has/had relatives in Minnesota where he immigrated. An ship passenger list that I think had him on it showed another Carlstrom with him. I can't locate it anymore, but if my recollection is correct it just used first initials, so I am uncertain if it is him.
Daniel Carlstrom Sr. resided in Montana where he resided for the rest of his life.
