Sigrid Eskilsdotter was the daughter of Eskil Isaksson (Banér) and Cecilia Haraldsdotter (Gren).
Her daughter Christina was the consort of the Swedish regent from 1512 to 1520 and the leader of the Stockholm resistance against Denmark in 1520.
Sigrid was sentenced to be sewn into a sack and drowned at sea, but the execution was interrupted when she agreed to bequeath all her assets to the monarch.
Together with her daughters Christina and Cecilia, and her granddaughters as well as a large group of Swedish noblewomen, Sigrid was taken to Blåtårn in Denmark in 1521.
Her daughter Cecilia and two of her granddaughters died in prison, but Sigrid was allowed to return to Sweden in 1523, where her grandson was now king.
