I want to know the answer to the following question:
DNA from Alexandre Colonna-Walewski's descendants has been used to confirm what attribute of Napoleon's?
All the background I'm provided with is that "He may have had further unacknowledged illegitimate offspring as well, such as Eugen Megerle von Mühlfeld by Emilie Victoria Kraus and Hélène Napoleone Bonaparte (1816–1907) by Albine de Montholon.". Is that enough to answer the question?
Answer: no
