  == Marquis of Parana ==   Hi Lecen,  I have a quick question:  Do you know anything regarding a connection between the family of the Marquis of Parana and the family of the Duke of Caxias? I know that the conservative families used to marry among themselves as did the descendants of Caxias that married into the family of Carneiro da Silva and later into the family of Eusebio de Queiros which was also connected to the family of the Baron of Tiete.   The only thing I remember reading about the descendants of Parana was that his daughters converted to protestantism and caused a lot of controversy.  If you know anything please let me know.  Regards,
