Carl Maximilian 1825-1905:

Military service, lieutenant; imperial and royal chamberlain, privy councillor, life member of the Austrian House of Peers
An agricultural innovator, he wrote Die Pflanzenernährungslehre mit Einschluß der Dün-ger- und Ersatzlehre. Für Landwirthe und landwirthschaftliche Lehranstalten – R. Olden-burg, Munich 1865, a book that made its mark despite its critical remarks on some au-thors of related literature.
Received the Liebig Medal in 1874, a decoration restricted to eight persons at a time > http://de.wikipedia.org/wiki/Justus_von_Liebig 

Joseph 1823-1868:

Imperial royal chamberlain, cavalry captain, humanist
Extensive oriental travels in the 1850s
Took over the estates after his father’s death in 1861 and gave most generously to Cath-olic causes in the face of some scoffing coequals, provided for the educational needs of poor children and supplied funds for the building or decoration of churches. In Bohemia, he was a member of the Moravian Diet and fought for the equal status and imprescriptible rights of the Crown of St Wenceslas within Austria-Hungary. In this respect he proved much more constitutionally constructive than the patchwork approach preferred by Em-peror Francis Joseph.

Joseph August 1793-1861:

Imperial royal chamberlain, royal treasury secretary, honorary curator of First Savings Bank Vienna, vice-president of the Choirmasters Association, commissary general of the First Austrian Steam Laundry and Bleaching Establishment
His penchant for genealogy was not matched by his critical spirit. Repeatedly he had to withdraw information he had supplied to the Gotha Almanac because of mystifications foisted upon him by hoaxers. When Austria and Her Future, a publication that found fault with the Metternich system, appeared in 1841 some pranksters spread the rumour that he had penned it. He sincerely hoped the chancellor of state would not hear of it. Metter-nich and his wife, however, were perfectly aware of Baron Victor Andrian’s authorship. > http://de.wikipedia.org/wiki/Victor_Franz_von_Andrian-Werburg 

Joseph Johann 1752-1838:

Studied at the Theresian Academy for Noble Youth, imperial royal cameral aulic councillor 1772, privy councillor and ambassador at the Bavarian Electoral Court 1790
He had to apply his energies to managing the financially compromised estates upon his father’s death in 1801 which prevented him from taking up his post as ambassador to Madrid. His initiatives proved exemplary and many of his subjects profited from them. Jo-seph II and Francis II (I) held him in high esteem; he took part in the Congress of Vienna as Charles, Grand Duke of Baden’s, lord high chamberlain between 1814 and 1815.

Maria Christiana 1854-1791:

Née Auersperg, Joseph John’s first wife 1776
Much admired as a paragon of noble virtues in her youth, she bore years of an incurable mortal illness in a manner that provoked widespread recognition and sympathy among most of those who knew her.
