In 1641, at the age of thirty-one, Susanna Margarete was betrothed to
John Ernest, Count of Hanau-Münzenberg-Schwarzenfels, the last male heir of the line of Hanau-Münzenberg; however, he died of
smallpox shortly before the wedding was to take place in 1642. In
Buchsweiler on 16 February 1651, Susanna Margarete married
John Philip of Hanau-Lichtenberg, younger brother of the ruling Count
Frederick Casimir, husband of her older sister
Sibylle Christine of Anhalt-Dessau. Probably on account of the substantial age difference between the spouses (Susanna Margarete was sixteen years older than John Philip), the marriage was childless. ==References==
