Beschon wrote a composition to Eleonora which he sent her along with a letter dated 28 February 1647, but she gave it to her brother; this document is now preserved in the Stegeborg collection.

Eleonora was nevertheless constantly pregnant, giving birth to six children in just seven years; only half of them lived to adulthood.

It is said she was too embarrassed by the scandal with Beschon to return to the Swedish court, so she preferred to live in her fief Osterholz, where she founded a pharmacy and hired the first teacher and doctor of the town.

Eleonora sent her daughter Juliana to be brought up at the Swedish royal court, where she was regarded as a prospective bride for Charles XI until she became pregnant in 1672.

During her 1674 visit, Lorenzo Magalotti described her as "a wicked, vain, strange, proud and melancholic woman" who spent most of her time in pious devotions.
