Margaret of Ravensberg

However, when Bernhard died in 1346 without issue, Margaret became the heiress of Ravensberg, her elder sister and only sibling, Hedwig, having died in 1336.
Then, when Margaret's uncle, Adolf IX of Berg, died in 1348 without issue, Margaret also inherited Berg by right of her mother, since Margaret was Adolf's only surviving niece.
As a result of her marriage to Gerhard VI of Jülich, Berg and Ravensberg passed into the house of Jülich where they remained until 1511 when they passed into the house of Cleves.
