He eloped to Switzerland with Countess Marie d'Agoult. Their idealistic
relationship eventually disintegrated in 1844. Together, he and
d'Agoult had three children: daughters Blandine (b. 1835) and Cosima
(b. 1837), and son Daniel (b. 1839). Daniel died in 1859 at the
age of 21. Liszt would write "Two Episodes from Lenau's Faust"
and "Les Morts" to honor his memory. In 1862 his daughter Blandine
died in childbirth. His other daughter, Cosima, later left her husband
to be with composer
Richard Wagner, to whom she bore daughters Isolde in 1865
and Eva in 1867 and son Siegfried in 1869 before they finally married
in 1870.
