Queen of Sweden. With approximate years of birth and death given here, her original West Slavic heritage as a Princess of the Obotrites, in what now is Mecklenburg in northern Germany, is recorded in several sources. It can be assumed with reasonable certainty that she belonged to the early Nicholan Dynasty, and it is likely she was born near Schwerin. After the Battle of Swolder in 1000 she married the important Swedish ruler Olaf (V) Scotking and became his Queen Consort. Their son Anwynd James (Anund Jakob) was born around 1007. His double name, half pagan, half Christian, was created for diplomatic reasons and constitutes a start of the double first names that have been used by millions in the subsequent Swedish population. A year later Princess Ingigarth was born and the whole family was baptized by St. Siegfried at Husaby. Estrith saw her daughter's hand declined the suit of King Olaf II the Holy of Norway, whom her husband vehemently hated, but granted Great Prince Yaroslav I of far-away Kiev in 1020. According to Snorri Sturluson, Queen Estrith was "haughty and unkind to her step-children", King Olaf's earlier offspring by his official concubine Lady Ethel. To spare his elder son the problem, Olaf had had to send the future King Edmund (III) away to Lusatia to be brought up by Ethel's family. The queen was widowed two years after Ingigarth's wedding and probably survived Olaf by about a decade, passing away well into the reign of King Anwynd (IV) James. Due to his reported blindness, and in spite of his "golden clothing", the new king's unsuccessful war campaign to the Ukraine in 1024 to aid his brother-in-law against insurgents must have worried his mother at home. The burial of Estrith and Olaf near the sacred spring where they had been christened is related in later records, and the age of grave monuments found at Husaby Church coincides.
