Thyra Haraldsdottir
Thyra Haraldsdottir (died 18 September 1000) was a 10th century Danish shieldmaiden and the bastard daughter of King Harald Bluetooth. While their relation was not a secret, Thyra despised her coward father and never asked Harald to publicly acknowledge her as his daughter
After her father married Gyrid of Sweden and allied with his wife's brother, Styrbjörn the Strong, Thyra joined the army who fought against King Eric of Svealand to give back the throne to Styrbjörn. After Harald betrayed Styrbjörn and left with all the Danes under the cover of the night, Thyra opted to stay with the Swedish Prince. During the campaign against Eric, Thyra married Styrbjörn, with whom she sired a child the night prior to his death, and is thus an ancestor of Sean Molloy.
