Viking Estrid Not Mother but Daughter

In an article for New Scientist, researchers disclose that the female remains buried with the last Viking king were not those of his mother as previously believed, but in reality, his daughter-in-law.

DNA testing on teeth in the grave of Sven Estridsen, who died in 1074, show that the female skeleton buried nearby could not have been his mother Estrid, but are more likely those of one of his daughters-in-law who was also named Estrid.
