Richardis of Bavaria

[1] Richardis married Otto I of Guelders, and after his death became the first abbess of the Cistercian Abbey of Roermond.

She died in 1231 and was buried in the Church of Our Lady, today the only surviving part of the abbey.

Their known children are: Henry, who died young, shortly after his engagement to Aleidis (born c. 1186), daughter of Dirk VII of Holland;[4][5] Gerard, the Count of Guelders and Zutphen;[6] Otto, who is recorded as Otto I's brother in one document[7] and was Provost of Xanten before becoming Bishop of Utrecht at a very young age; Irmgard, Margaret, Matilda, and Adelaide, who married William I of Holland.

Ten years after her husband's death, Richardis wanted to join this order.

Her grandson Otto II Count of Guelders and Zutphen granted Harderwijk city rights in 1231.
