Margareta von Neu-Kyburg
Margareta von Neu-Kyburg (c. 1272–1333) was the second wife of Count Dietrich VII of Cleves. Daughter of Eberhard I of Habsburg-Laufenburg and Anna of Kyburg, she was kinswoman to the Habsburg kings. After Dietrich's first wife died, she married him in 1290; that year Rudolf granted Dietrich Duisburg.
When her stepson Otto succeeded his father in 1305, he faced claims from Margareta and her sons Dietrich and John. Both sons later ruled Cleves. Margareta died at Kleve in April 1333.
