As they have for 105 years, the members of the San Rocco di Simbario Society will embark on a five-and-a half-hour procession through the streets of Chicago’s Chinatown to honor the patron saint of their ancestral hometown. In the process, they’ll be celebrating their Catholic faith and maintaining a tradition now entering its fifth generation.

“It’s based on devotion, it’s religious, spiritual and it’s about family,” says Frank Bertucci, the society’s treasurer. “My daughter told me, as we walk through the streets of the old neighborhood, it’s like a walking family reunion. We see people we’re related to and even if we’re not related, our families have known each other for three or four generations.”
