Eadgyth

Edith of England , also spelt Eadgyth or dgyth, was the daughter of Edward the Elder, and the wife of Otto I, Holy Roman Emperor.

Edith was born to the reigning English king Edward the Elder by his second wife, lffld, and hence was granddaughter of Alfred the Great. Nothing is known of her until in order to seal an alliance between two Saxon kingdoms, her halfbrother, King Athelstan of England, sent two of his sisters to Germany, instructing the Duke of Saxony to choose whichever one pleased him best. Otto chose Edith and married her in 930. The remaining sister Algiva or Adiva was married to a king near the Jupiter mountains . The precise identity of the husband of this sister is debated.
