Searching for my anscestors too. Ws told by my family that grandmother's 2nd cousin was Pope Leo the thirteenth. His last name was Pecci, and so was hers. His mother's last name was Prosperi. She descended from nobility also. The family of Cola di Rienzo. That is a fashionable shopping street in Rome. I saw it 2 years ago. Would like to get a lineage done. someone on Ancestry. said the vatican doesn't have one. You were probably looking for someone a little more recent, but you may be related to one of the most famous popes of all time.
