[2] In view of her German name, Emnilda's mother possibly was the member of a Saxon comital dynasty.More citaeded However, other historians have argued for a different background.
During her marriage, Emnilda bore her husband five children, two sons (the future Mieszko II Lambert and Otto)[3] 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.
She was mentioned by Gallus Anonymus and Thietmar of Merseburg; both chroniclers noted she was a wise and charming person and no negative opinion of her can be found in the historic sources.
She probably accompanied Bolesław to the meeting with Henry II at Merseburg on 23 May 1013 and perhaps she actively promoted the recognition of their son Mieszko II as a vassal of the Emperor for his government over Moravia,[citation needed] a fact who put in jeopardy the succession rights of Bolesław I's eldest son Bezprym, who at the end was excluded in favor of his younger half-brother.
The exact date of Emnilda's death is unknown, but is assumed that this happened in 1017 at the latest, or, more likely, at the end of 1016, because on 3 February 1018 Bolesław I married with his fourth and last wife, Oda of Meissen.
