Estrid combines the Old Norse áss (god) and fríðr (fair, beautiful) — "fair-as-the-gods." **Estrid Svendsdatter (c. 990-c. 1057)** was the daughter of King Sveyn Forkbeard of Denmark and sister of Cnut the Great — mother of King Sveyn II, **founder of the Danish royal dynasty that ruled into the modern era.**
Buried at Roskilde Cathedral.
Estrid reduces to one — the number of Danish dynasty.
