Margaret's father, Otto, had no sons, so at his death in 1328, the County of Ravensberg went to his younger brother Bernhard.
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.

Gerhard was betrothed in 1333 (renewed 1342) to Margaret of Guelders, daughter of Rainald II of Guelders and Sophia Betrout.
However, this marriage was never consummated, likely due either to Rainald's death in 1343 or Margaret's death in 1344.<br>
Gerhard was subsequently married about 1344 to Margaret of Ravensberg, heiress of Berg and Ravensberg (died 13/19 February 1389), daughter of Otto IV, Count of Ravensberg and Margaret of Berg.
