Princess Margrethe and Prince René settled in Paris after their marriage. They didn't have much to live on, and after Hitlers invasion of Paris in 1941 they had to flee the city and Margrethe had many difficulties securing the families safety. After getting financial help from her sister-in law, Grand Duchess Charlotte of Luxembourg, the family moved to USA. Her she took a job in a department store until 1945 when the family moved to Denmark. After Prince Renés death in 1962 she moved around from place to place staying in France, Monaco and Denmark.
Life wasn't always easy for this high spirited lady, but she took it with her good humor and strenght. She said
"I had to sell all my jewelry, and when I had to dress up, I borrowd from Princess Margaretha (whom she was very close to). I have always been more interesed in travelling, then spending money on close."
