Have you seen the story of Max Galuppo? www.huffingtonpost.com/2012/11/14/max-galuppo-temple-university-twin_n_2130291.html
Basically, Max ran into a 16th century Italian painting in a Philadelphia art museum, and the subject appears to be his identical twin. The Nobleman in the portrait was from the same region that the Galuppo ancestors are from. They are looking deeply at the family tree now. I love this stuff!
