Sander discovered numerous similarities between the young Margaretha of Waldeck and the Grimm Brothers' heroine.
- Margarete had an antagonistic relationship with her stepmother.
- At the age of 16, the girl was forced to leave her home in Germany and live in Brussels.
- Her father, Philipp IV of Waldeck-Wildungen, owned copper mines worked mainly by children. Because of poor working conditions, many died young, but those who lived suffered from malnutrition and stunted growth. They were scornfully referred to as “poor dwarfs”.
- Margarete had a love affair with a prince (Philip II-- the future King of Spain). The relationship was frowned upon by his relatives since no political benefit would have been gained through marriage.
- To do away with Margarete, it is thought that she might have been poisoned at the age of 21.
