Caroline Lacroix
She and Leopold married in a religious ceremony five days before his death. The did not have a civil ceremony so the marriage was not legal under Belgian law. After the king's death, it was learned that he had left her many properties, items of high value and other valuable sources of income. All of this turned her into a multimillionaire. For years, the Belgian government and Leopold's daughters tried to recover some of these items. They had varying ammounts of success. Caroline died on 12 February 1948 in Cambo-les-Bains, France.
