I am searching for information about my maternal grandmother, Mathilda Charlotta (Swenson) Forsberg.

A family report says she arrived in Kasota, Le Sueur County, Minn. in 1880 at the age of 16, but the census says she arrived in 1885 at the age of 21.

She married my grandfather, Adolph Fredrik Forsberg on November 9, 1887 in St. Peter.

I would appreciate any information about her arrival in Kasota and any other information about her.
