as they looked very much alike, witnesses were confounded and their testimonies deemed unreliable. Count Bacinetti, the key witness, was not liked by Duchess Louise Marie, who had him expelled from Parma. Bochi and Carra acted not for political reasons, but for financial gain. It was never clarified who paid them to kill the Duke. Ancestors Patrilineal descent Charles's patriline is the line from which he is descended father to son. Patrilineal descent is the principle behind membership in royal houses, as it can be traced back through the generations – which means that if Duke Charles were to choose an historically accurate house name it would be Robert, as all his male-line ancestors have been of that house. Charles is a member of the House of Bourbon-Parma, a sub-branch of the House of Bourbon-Spain, itself originally a branch of the House of Bourbon, and thus of the Capetian dynasty and of the Robertians. Charles's patriline is the line from which he is descended father to son. It follows the Dukes of Parma as well as the Kings of Spain, France, and Navarre. The line can be traced back more than 1,200 years from Robert of Hesbaye to the present day, through Kings of France & Navarre, Spain and Two-Sicilies, Dukes of Parma and Grand-Dukes of Luxembourg, Princes of Orléans and Emperors of Brazil. It is one of the oldest in Europe.
