1910 living Porter Township, Rock County, Wis (Age 31 ( On 3 May), married 8 yrs). 1537

1920 living Fergus County Montana (Age 29 on 10 Jan). 845

This is an educated guess on her last name and her parents names. The 1920 census said she was born in Wisconsin about 1890, and that both her parents were born in Norway. There were only four families in Rock County that had a daughter named Jennie with both parents porn in Norway. Looking at everything this seemed the most logical since they lived very near Winnfield Smart.
The Last name of each are:
Fuseth
Halland
Jeppson
Berg
I was unable to prove that any of these were the correct Family.1540
