More 'Dumas dates'

( Further historical incompatibility )

But the error is quite definitely that of Dumas, who refers multiple times to the mother of Louise in Twenty Years After as "Madame de Saint-Remy", and canon trumps history every time. In Dumas' universe, Louise (born August 1644) is already seven in 1648 and has a stepfather -- and the events of 1661 are stated to take place ten years after those of 1649, which is how Louise manages to be seven in the first book despite being historically seventeen at the time of the second :-D
