Newspaper announcement, Correspondenten - Skien, Jan 25th 1849; "The new ship Valhalla which has just returned from the Mediterranean with a load of salt for the second time, and which is rated 1st class by the Norwegian insurance company, with a burden of 181½ commercial lasts, is by the owner Hans Wallø of Tønsberg decided to depart from Skien to New York with passengers in May. The ship which is mastered by Capt. O. M. Bjerke, is an excellent sailor, and is very well fitted for carrying passengers, for whom the accommodations are in all ways cared for. Anyone who wants to take the advantage of this good opportunity, must as quickly as possible make contact with Mr. Knud Ibsen in Skien, where enrolling is taking place. The fee will be discussed closer, and will be as low as possible." - The Valhalla departed from Skien on June 6th carrying 168 passengers. Master was Capt. Bjerke. She arrived at New York Aug. 10, the passenger manifest is dated Aug 11. (archived by NARA) The total value of the cargo was 3000 $.

Newspaper announcement, Correspondenten Feb 25th 1852; "If a sufficient number of passengers signs on as soon as possible, to go to America via Quebec, It will be good and reasonable accommodation available on the ship Walhalla, Capt. Bjercke. Please approach merchant Jørgen Halvorsen in Skien for further details and enrolling." Because the National Archives of Canada [NAC] did not start the archiving of passenger lists before 1865, and the Norwegian emigration records did not start before 1867, there is no surviving passenger list for this voyage in any of those archives.
