Let's go by last names of my 2x great-grandparents
Ferraiolo: Ummm....Does my dad's office count? He does have a dental practice on a main street in Salem.
Coppola: The Coppola bus company in Haverhill, Massachusetts was founded by and named after my first cousin 3x removed, Frank Coppola. And that's Co-poh-lah. Not the pretentious way Frances Ford Coppola pronounces it. Just getting it out there. No one else but him pronounces it that way. But, yeah. The school bus company is named after him and still operated despite the hands changing.
That's probably it for the Italian side. You'd be hard-pressed to find stuff named after Tedesco, Gullo, Carrabs and Capobianco.
Hamel: There's a Hamel health center at Merrimack College. I don't know if there's a connection to me. That might be a bit of a stretch. Though, I am pretty sure there might be some places in Quebec named after the two Hamels who were among the first two hundred or so people who colonized Quebec. I descend from Charles Hamel.
Of course there's also Hamel Reality that my cousin owns and operates. =)
Can't think of much else on my mother's side. Though, I do have some famous names WAAAY back on her side. We're talking the 1600s here.
Tufts Academy was founded by a relative.
The Pillsbury company, too. Fun story. Someone on Ancestry put the Pillsbury logo in as a profile pic. It wasn't me! (I wish it was because that is so totally something I would do.)
The Coffin House was named after Haverhill founder Tristram Coffin and his sons.
Some places in Salem, Mass are probably named after Thomas Putnam who was an ancestor of mine.
There's more. My mom has a veritable who's who in her tree.
