MORE BERTHIER INFORMATION
I just received the following information.
Remember this is from family notes from 1932:(not always reliable information)
Sarah Berthier was said to have been closely related to General Alexander Berthier b. Feb 20, 1753 Versailles France d. 1815 Bamberg, Bavaria.Notes say Napoleon had him marry Princess Elizabeth Marie, niece of King of Bavaria "we have his royal children"
That is all the note says.
