Grandmother's Ship?

I'm trying to determine the name of the ship my paternal grandmother, Julia Christina Williamson, took to America. Her name is given in the 1900 Census as Gurine Kristine Velhelmsdatter, on the Haug farm, near Tysse, Samnanger. She was the youngest daughter of Velhelm Knudtsen (1830 - ?) and Gunille Axelsdatter (1847 - ?). My grandmother was born on 3 Dec 1888, so she would have been about 17 when she immigrated, I believe, in 1905. She settled in Grundy/Kendall Counties, in Illinois, married Thomas Elias Hagen prior to 1912. Thanks much for your help!
