Enfant(s):
Duke Alexander of Württemberg (Mömpelgard/Montbéliard, then Württemberg (now France), 5 May 1771 - Gotha, Thuringia, Germany, 4 July 1833) was a Duke of Württemberg. The son of Frederick II Eugene, Duke of Württemberg and of Sophia Dorothea of Brandenburg-Schwedt. His sister Sophie Dorothea married Tsar Paul I of Russia.
In 1798 he married Antoinette of Saxe-Coburg-Saalfeld (1779 - 1824). They had five children:
Marie of Württemberg (1799-1860), who in 1832 married Ernest I of Saxe-Coburg-Gotha.
Paul of Württemberg (1800-1801)
Alexander of Württemberg (1804-1881), Duke of Württemberg
Ernest of Württemberg (1807-1868), Duke of Württemberg, who in 1860 married Nathalie Eschborn, later ennobled as "von Grünhof" (1829-1905) : Alexandra Nathalie Ernestine von Grünhof (Wiesbaden, 10 August 1861 - Hohenlübbichow, 13 April 1933), who in 1883 married Robert von Keudell
Friedrich Wilhelm Ferdinand of Württemberg (Saint Petersburg 29 April 1810 - Saint Petersburg, 25 April 1815)
Alexander of Württemberg was the founder of the fifth branch (called the ducal branch) of the House of Württemberg, descended from the seventh son of Frederick II Eugene, Duke of Württemberg. On the extinction of the eldest branch in 1921, the ducal branch became the new dynastic-branch of the House. (The House of Württemberg's two morganatic branches - the dukes of Teck (extinct in the male line in 1981), and the morganatic branch of the dukes of Urach - were technically 'older' than the Ducal branch, but ineligible to succeed).
Alexander of Württemberg is the direct ancestor of the present claimant to the dukedom of Württemberg, Carl.
