Astrid Mathiesen in May 1914, Kristiania->Hull?

Hi, I know from records that Astrid Ovinda Mathiesen, B 29 Jul 1894 went on the S/S Virginian, departing Liverpool, England on 13 May 1914 and arriving in Montreal, Quebec on 21 May 1914 from there Astrid arrived in Buffalo, New York on 23 May 1914. Now back-tracking this ... To get to Liverpool in May of 1914 she must have gone from Kristiania to Hull then overland to Liverpool. (I believe there were no direct voyages from Kristiania to Liverpool in May 1914) There are two possible ships from Kristiania to Hull in May of 1914 - 1914-05-06 S/S Eskimo 1914-05-08 S/S Spero (1) But I cannot find any passenger list info on this - does anyone else have this data? Any help very much appreciated ! [:)] Thanks.
