Was he the link to Us?

In 1875 Pernille Pedersdatter workt at Ladengen farm, Lom. At the same time there was a man called Ole Knudsen temporary living there. He was born in Lom but lived in Illionois. He was a stonecarver? marble? I wonder if this man took Pernille to US since I cant find more about her after 1875 and I know for sure she left for Amerika? Anyone who knows something? Gittan
