Estrid (Old Norse: Æstriðr, Ástríðr) was a rich and powerful 11th-century Swedish woman whose long family saga has been recorded on five or six runestones in Uppland, Sweden. This Estrid was the maternal grandmother of the chieftain Jarlabanke of the Jarlabanke clan. The family were rich landowners and belonged to the higher echelons of Swedish society. Her family saga has been the centre of a dramatisation at the Stockholm County Museum. . https://en.wikipedia.org/wiki/Estrid
