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.
A sixth runestone, U 329,[2] deals with an Estrid who is only mentioned as the sister of a Ragnfast and a Gyrid.
This would mean that Estrid was born in Snottsta (also spelled Snåttsta) as the daughter of the rich landowner Sigfast.
[6] The story of her life is continued on the Hargs bro runic inscriptions,[7] where we learn that Estrid had married a man named Ingvar, and this Ingvar had a son prior to marrying Estrid whose name was Ragnvald.
When Stockholm County Museum made an archaeological excavation at Broby bro, in 1995, they found three graves.
