It seems we're certainly related. (If I have this right, we're second cousins, once removed) I was born in Rhinelander. Lawrence and his wife Catherine Gorichs had five children, all of whom are dead now. They were:
Margaret Laverne (b. 1914) LeRoy Carlton (b 1915) Florence Carabell (b. 1918) Rosaly Kathleen (b. 1920) and Ervin Lawrence (b. 1924)
That visitor might well have been my aunt Laverne because she also worked at the Fergus Falls State Hospital from about 1930 to 1940.
And you had some of Carl's children right, but there are additions! They were: (in Carl's spelling from a remnant of the family bible):
Thorsten Johannes (b.1975) Lina Elise (b. 1877) Josefine Christine (b. 1879) Hans Julius (b.1881) Klara Matilde (b. 1883) Sara Laurense (b. 1885) Edvin Kalmar (b. 1887) Lorens Enok (b. 1889) Ole Egnar (b. 1892) May Kattinka (b. 1897)
I drove by the farm, (or what I THINK is the place) one day last year, and saw the graves of both Carl and Hans at the Trefoldeghet Menighet nearby. There's also an abandoned school nearby that my dad attended.
Thanks for responding! Perhaps you know about it, but there's a nice resource in a book published in 1916 entitled "History of Otter Tail County Minnesota" by John W. Mason. There's a sketch in there about Carl and his family (though misspelled as "Thorstonson") and also lists Hans and Carl's siblings back in Norway. Most interesting is the mention of another brother named Jens "...who came to America, served in the Civil War, and promoted to captain, but never returned..." I've never been able to dig anything up about this fellow.
I'd also be interested in knowing how long the farm stayed in the family. It looks like really pretty country out there!
