[2] Bishop Gunner of Viborg had first thought of the idea of the marriage, as Eleanor's aunt Berengaria had been Valdemar's stepmother.

Only two years later Eleanor died in childbirth on the 28 August 1231, and three months later her husband was killed by an accidental shot.

When examining Eleanor's grave in Ringsted Church, it was discovered that her skeleton showed traces of cancer of the bones, which probably was contributory to her death.

At the foot piece of Eleanor's grave was a leaden coffin, which contained the bones of a child about 6 months old, already sickly and scrofulous from birth.

So Eleanor probably gave birth to a child, who survived her by only six months.
