Is Prince Amedeo a descendant of Lucrezia Borgia through his father's side? I'm just wondering because I read somewhere in the internet that Lucrezia married an Este...
Prince Amedeo is a direct descendant of Lucrezia Borgia through numerous different lines, both on his maternal and paternal sides.
The "Este" in his surname has little relevance to Lucrezia though.
One of matrilineal lines of descent through which Prince Amedeo is Lucrezia's 16th great-grandson:
Lucrezia Borgia -
Ercole II d'Este -
Anna d'Este -
Charles de Lorraine, Duke of Mayenne -
Catherine de Lorraine -
Anna Gonzaga -
Countess Palatine Anne of Simmern -
Louis III, Prince of Conde -
Louise Elisabeth de Bourbon -
Louise Henriette de Bourbon -
Louis Philippe II, Duke of Orleans -
Louis-Philippe I, King of the French -
Princess Louise-Marie of Orleans -
Prince Philippe, Count of Flanders -
Albert I of Belgium -
Leopold III of Belgium -
Albert II of Belgium -
Princess Astrid of Belgium -
Prince Amedeo
Virtually
all of modern European royalty, current and abolished, is descended from Lucrezia Borgia.
