Coudenhove-Kalergi
Coudenhove-Kalergi is a noble Bohemian family of mixed European descent formed when Franz Karl Coudenhove (1825-1893) married Maria Kalergi (1840-1877). The Coudenhoves had been Counts of the Holy Roman Empire since 1790 and rose to great estate in the Netherlands and Belgium. After the upheaval of the French Revolution, they followed their dukes from the Low Countries into Austria. Maria's family enjoyed high status in Crete.
