Adelheid of Wittgenstein

Adelheid of Wittgenstein (died between 1357 and 1362) was the daughter of Count Siegfried III of Wittgenstein and Margareta von Schönecken. In 1359 her brother Count Werner IV and then her father died, ending the male line of the Wittgenstein counts and leaving Adelheid as heiress of the county.

She was married to Salentin von Sayn-Homburg, who took possession of Wittgenstein in 1361 and founded the House of Sayn-Wittgenstein. Her son John IV later ruled the county.
