I am in the midst of research fro a book and was reading through the biography 'Marie-Therese The fate of Marie Antoinette's Daughter' by Susan Nagel.
I like to consider myself reasonable knowledgeable on the life of MA and her family but something in this book has bugged me.
It is the first and only time that an author has mentioned this half-sister named Ernestine that Nagel implies was the offspring from an illicit affair Louis had with Madame du Polignac.
Apart from finding this completely implausible I am surprised it be mentioned in an actual historical biography which presumably is based on fact...any thoughts.
There is a lot of information on the internet about Ernestine Lambriquet. She was a legally adopted daughter of queen Marie Antoinette. She married in 1810 and died in 1813. Her burial place is known. There were rumours that she was an illegitimate daughter of the king, but these were never proven.
