In page Emnilda:

"

The wedding of Emnilda and the heir of the Polish throne, Bolesław, took place around 987.[citation needed] It was the third marriage for the young prince: his previous two wives, the daughter of Margrave Rikdag of Meissen (perhaps called Hunilda or Oda) and the Hungarian princess Judith, were repudiated after few years, but both produced offspring to Bolesław, a daughter and a son, Bezprym. During her marriage, Emnilda bore her husband five children, two sons (the future Mieszko II Lambert and Otto)[1] and three daughters, one of them became an abbess and the other two, Regelinda and Amelia were married to Margrave Herman I of Meissen and Grand Prince Sviatopolk I of Kiev, respectively.
