[citation needed] After the king's wife, Queen Louise (1812–1850) died, Meyer returned to Brussels in 1851 and started to conduct herself and her affair more discreetly.

[citation needed] She moved out of the house on the Rue Royale and bought the Château of Stuyvenberg with the king's financial aid.

[citation needed] King Leopold wanted to bestow a title on his unofficial family and create them barons of Eppinghoven, which the Belgian parliament refused to approve.

[citation needed] In the end, in 1862, Leopold's nephew, Ernest II, Duke of Saxe-Coburg-Gotha granted the hereditary title to two sons, and in 1863 to their mother, too.

[citation needed] The Baroness d'Eppinghoven had started building a castle in Monheim am Rhein in 1862, where she retired following the death of the king, seeing that she was no longer welcome in Belgium.
