Sweyn Forkbeard was King of Denmark from 986 to 1014, also at times King of the English and King of Norway. He was the father of King Harald II of Denmark, King Cnut the Great, and Queen Estrid Svendsdatter.
Harald "Bluetooth" Gormsson was a king of Denmark and Norway.
Richeza of Poland, a member of the House of Piast, was twice Queen of Sweden and once Princess of Minsk through her three marriages.
Sweyn II Estridsson Ulfsson was King of Denmark from 1047 until his death in 1076. He was the son of Ulf Thorgilsson and Estrid Svendsdatter, and the grandson of King Sweyn I Forkbeard through his mother's line. He was married three times, and fathered 20 children or more out of wedlock, including the five future kings Harald III Hen, Canute IV the Saint, Oluf I Hunger, Eric I Evergood, and Niels.
Eric the Victorious was a Swedish monarch as of around 970. Although there were earlier Swedish kings, he is the first Swedish king in a consecutive regnal succession, who is attested in sources independent of each other, and consequently Sweden's list of rulers usually begins with him. His son Olof Skötkonung, however, is considered the first ruler documented to definitely have been accepted both by the original Swedes around Lake Mälaren and by the Geats around Lake Vättern. Adam of Bremen reports a king named Emund Eriksson before Eric, but it is not known whether he was Eric's father. The Norse sagas' accounts of a Björn Eriksson are considered unreliable.
Sigrid the Haughty, also known as Sigrid Storråda (Swedish), is a Scandinavian queen appearing in Norse sagas. Sigrid is named in several late and sometimes contradictory Icelandic sagas composed generations after the events they describe, but there is no reliable historical evidence correlating to her story as they describe her. She is reported by Heimskringla to have been wife of Eric the Victorious of Sweden, sought as wife by Olaf Tryggvasson, then married to Sweyn Forkbeard of Denmark, but elsewhere author Snorri Sturluson says that Sweyn was married to a different woman.
Gytha Thorkelsdóttir, also called Githa, was a Danish noblewoman. She was the wife of Godwin, Earl of Wessex and the mother of King Harold Godwinson and of Edith of Wessex, who was the queen consort of King Edward the Confessor.
Emund the Old or Edmund was King of Sweden from c. 1050 to c. 1060. His short reign was characterised by disputes with the Archbishopric of Bremen over church policies, and a historically debated delimitation of the Swedish-Danish border.
Świętosława is the name some historians have assigned a Polish princess, the daughter of Mieszko I of Poland and sister of Bolesław I of Poland, who married two Scandinavian kings. According to German chroniclers, this princess, whose name is not given, was married first to Eric the Victorious of Sweden and then to Sweyn Forkbeard of Denmark, giving the former a son, Olof, and the latter two sons, Harald and Cnut. Because a documented sister of Cnut seems to have borne the Polish name Świętosława, it has been speculated that this may also have been the name of their mother, the Polish princess of the chroniclers.
Helena or Elin, possibly also known as Maer, Mär or Mö, was Queen of Sweden as the wife of King Inge the Elder, and a supposed sister of King Blot-Sweyn of Sweden.
Gunhilda of Denmark, was Queen consort of Germany by her marriage with King Henry III from 1036 until her death.
Gunnhildr konungamóðir or Gunnhildr Gormsdóttir, whose name is often Anglicised as Gunnhild is a quasi-historical figure who appears in the Icelandic Sagas, according to which she was the wife of Eric Bloodaxe. She appears prominently in sagas such as Fagrskinna, Egils saga, Njáls saga, and Heimskringla.
Gunhilda of Wenden was a Polish princess, daughter of Mieszko I of Poland according to Chronicles of Thietmar of Merserburg, Adam von Bremen and Acta Cnutonis regis princess and Danish Viking Age queen consort, the supposed spouse of 10th-century King Sweyn I of Denmark. The sources about the wife or wives of Sweyn are contradictory, and historians have debated the whether she is the Polish Świętosława given another name in Norse sources.
Elin Ulfsdotter Snakenborg, Marchioness of Northampton, also known as Helena, and Helena the Red for her red hair, was a Swedish-born noblewoman, Maid of Honour of Queen Elizabeth I of England, and Marchioness of Northampton by her marriage to William Parr, 1st Marquess of Northampton.
Estrid Svendsdatter of Denmark, was a Danish princess and titular queen, a Russian princess and, possibly, duchess of Normandy by marriage. She was the daughter of Sweyn Forkbeard and perhaps Gunhild of Wenden and half-sister of Cnut the Great. By Ulf Jarl, she was the mother of the later King Sweyn II Estridson and Beorn Estrithson. The dynasty that ruled Denmark in 1047–1412 was named after her. Though never a ruler or wife of a king, she was known in Denmark as queen during her son's reign.
Gunnhildr Sveinsdóttir or Gunnhildr Haraldsdóttir, Guda or Gyda 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.
Helen, is the assumed name of a medieval Swedish princess and Danish queen, Queen consort of King Canute V of Denmark. The date of her birth is not known; her father was King Sverker I of Sweden and her mother has been assumed to be Sverker's first spouse, Queen Ulvhild.
Gyda Anundsdotter of Sweden, also known as Guda and Gunhild, was a medieval and Viking Age Swedish princess and Danish queen consort, spouse of King Sweyn II of Denmark.

The Danish House of Knýtlinga was a ruling royal house in Middle Age Scandinavia and England. Its most famous king was Cnut the Great, who gave his name to this dynasty. Other notable members were Cnut's father Sweyn Forkbeard, grandfather Harald Bluetooth, and sons Harthacnut, Harold Harefoot, and Svein Knutsson. It has also been called the House of Canute, the House of Denmark, the House of Gorm, or the Jelling dynasty.
