Hvem daterede Svend Estridsen?

Svend Estridsen eller Svend Estridsøn (Svend 2., i samtiden også kaldet Svend den Yngre; født ca. 1019, død 28. april 1076 i Søderup, Hjordkær Sogn, Sønderjylland) var konge af Danmark fra 1047 til sin død.

Gunnhildr Sveinsdóttir or Gunnhildr Haraldsdóttir, Guda or Gyda (traditionally died in Gudhem, Västergötland, Sweden, c. 1060) was, according to the traditional view, a queen consort of King Anund Jacob of Sweden and of king Sveinn II of Denmark. However, the sources are so vague that several modern historians maintain that there were actually two queens of that name, of Sweden and Denmark respectively. She is sometimes called Gude or Gyridje, but this is probably because of confusion with her daughter, Gyda, who is also known under her mother's name Gunnhildr.
