They're sprouting locally, small yet official-looking signs that proclaim an otherwise anonymous intersection is the Thomas F. Coughlin, or Wilfred "Freddie" Suozzo, or Edward Everett square. "Who are they?" you might ask. We toured them and others to find out.

Cambridge seems to have more squares than nearby towns, with some intersections accommodating two squares and one corner. The one thing they all have in common is that they commemorate someone who made a difference to the community, no matter how small. Behind every name is a story, whether it's that of a governor or a grocer. The next time you're wondering about a square's namesake, ask a local merchant or neighborhood resident and you might hear a surprising tale.
