Princess Märtha of Sweden
In Sweden she stayed at first at a tourist hotel in Sälen, before travelling on to Stockholm where her parents and relatives lived.  Her presence in Sweden became problematic where some considered her presence to put Sweden's neutrality in jeopardy. President Roosevelt then offered her a personal invitation to the United States.  Her uncle, King Gustav V of Sweden, telegraphed her father-in-law King Haakon and advised against the trip, but Märtha insisted on accepting the invitation.  Roosevelt sent the US Army transport  to the then Finnish port city of Petsamo to pick her up. In the U.S., she and her children initially stayed at the White House. Crown Prince Olav, however, accompanied his father to the United Kingdom with the Norwegian government-in-exile. Thus the Norwegian royal couple, like many other couples during that time, were separated for much of the war.
