- Born: Abt 1050, Norway
- Died: 1066, Orkney Islands, Scotland about age 16
Maria may be Ragnhild Maria Haraldsdatter, who married Gudrod Crowan, King of the Isle of Man. Her mother may in fact be Elisabeth of Kiev.
Many internet postings show the two daughters, Maria and Ingegerd as being the offspring of Elizabeth of Novgorod, however, their estimated births are well after the marriage of King Harald and his 2nd wife, Thora. The sons, Olav and Magnus, have birth dates that coincide with the Harald's 1st marriage, to Elizabeth, and are shown as such in this history. Brian Tompsett says Ingegerd married first Oluf I of Denmark with whom she had a daughter Ulfhild, and later married Phillip of Sweden.
It is stated in the Rissa bygdebok for the farm Rein, that Maria died in the Orkney Islands the same day, and hour, that her father, Harald died at Stamford Bridge. It states:
Olav Kyrre was, as the nickname describes, more peaceful than his father Harald Hardråde. It was Olav “The Peaceful” who had the first Christian church built at Nidaros (Trondheim). “The Brutalruler”, Harald, lost his life in the battle of Stamford Bridge in 1066 in an attempt to win the British Throne. Olav sailed with his fleet from England from Hrafnseyr, and came in autumn to the Orkney Isles, where the event had happened that Maria, a daughter of Harald Hardråde, died a sudden death the very day and hour her father, King Harald, fell. Olaf remained there all winter; but the summer after he proceeded east to Norway, where he was proclaimed king along with his brother Magnus. King Harald's wife, Queen Ellisif came from the West, along with her stepson Olaf and her daughter Ingegerd.
