Princess Ileana and Prince Mircea, two of the children of King Ferdinand and Queen Marie of Romania (the latter was formerly Princess Marie of Edinburgh and then Saxe-Coburg). Ileana (1909-1991) was the youngest of their three daughters and went on to marry Archduke Anton of Austria, Prince of Tuscany. Mircea (1913-16), the couple's youngest child, tragically died of typhoid in 1916, with enemy troops advancing across the country and chaos all around. Soon afterwards, the family was forced to evacuate the palace and could not return for two years.
