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. Probably on account of the substantial age difference between the spouses (Susanna Margarete was sixteen years older than John Philip), the marriage was childless.
