Theodolinde, Countess of Wurttemburg..

.. and Napoleon 1st’s step-granddaughter, died very young, but first had 4 daughters who married well:

  •  Her firstborn married twice: 1st Count Rudolf von Enzenberg, etc. etc.; 2nd Count Franz von Thurn und Hohenstein, etc. etc. – NOTE:  This Thurn line combined with the royal blood of the Taxis line accounts for most of the royal lineage in Europe today!
  •  Her second was Marie Josephine of Urach
  • 3rd Eugenia Amalie of Urach
  • 4th Mathilde of Urach, who married Paolo, Prince of Oriolo & Viano

Theodeolinde’s husband remarried soon after her death.  The 2nd wife finally produced a boy and heir.
