Maren Petrine Brynlund's voyage to USA

Hello, Maren started her journey in Trondheim, Norway with the Wilson Line ship Salmo leaving Trondheim on the 8 of Oct 1902 for Hull in UK. From there she was going with a White Star Line ship to USA. Have not been able to find either the Port of Departure in UK or Port of Arrival in USA. On the registration card she had noted Mora, Minnesota as the final point of the journey. Maren Petrine was born in Herøy, Nordland, Norway 29 of Mar 1875 and died in Canada 10 of Jan 1942. Hope someone can give me a clue where to start the search to find the start and end of her voyage. Thank you Roar Brynlund
