If you go you can meet some of his relatives who knew him, namely, his grand nieces, now getting up there in age. I think of all the times I greeted Prince Francis Pacelli, deceased in 2011. He had been the head of the family, born in 1939; his passing was too soon.
Alas, the torch is passed to a new generation. The new head of the family is don Filippo's (born in 1941) son, Asciano Pacelli (born in 1973). His claim to fame is that he is a reality TV star in Italy on Grande Fratello (a an extremely popular show that was both shallow and annoying). Pray for his conversion.
