EDIT: "19.3.1909 tod. Amer" - this seems to tell that they indeed left country already in 1909 *
Finding her mother Erika ("Riikka") is easy (b. Jun 6 1870 Laukaa)

Father could be found here, "Niklas" (b. Jul 10 1866 [ elsewhere also written as "Jul 16", possibly a copy-error ] - his father is not known, mother servant Lena Mattsdotter, age 26):

Ellis Island passengers 1917 (ship name: United States): Erika Seppanen, Helvi(!) Seppanen and Jalmar Seppanen.
At that time husband "Niclas Seppanen" was already there (address: box 13, Arnold, Escanaba, Michigan), I just cant't find his immigration records right now, all too late here.
US census 1920 claims that the whole family has arrived already in 1909*:
County: Marquette
Place: Wells Township, Marquette, Michigan, United States
District: ED 255
State: Michigan
Marriage with William Johannes Johnsen Dec 16 1937:
