Sibylle married on 24 January 1505 to Count Philipp III of Hanau-Lichtenberg (18 October 1482 – 15 May 1538).

In 1514, Philipp was born and Sibylle donated a high altar to the City Church of St. Nicholas in Babenhausen.

This altar is considered a major work of art from the Middle Rhine area in this period (artist unknown).

The left wing of the altar depicts, among other people, her great-uncle, the blessed Bernard II, who was famous for his pious life and was beatified in the 18th century.

Sibylle died on 10 July 1518 and was buried in the family crypt of the Hanau-Lichtenberg dynasty in the City Church of St. Nicholas in Babenhausen, where her husband was later buried.
