Lots of transplants tend to mispronounce local street names or town names.

In Roslindale there is an Albano Street. It is "al-BAY-no" but those not born there say "al-BAN-no." As I tell them, it is not named after a former wrestling star (Lou Albano).

Some years ago my neighbor was stopped by a lost motorist and asked for directions to "muh-TAP-un." No one seemed to know where that was. After a little thought process he told the driver that he can't get there, because it is pronounced "MAT-uh-PAN" (Mattapan).

Directions were issued to the poor lost soul.

Boston and vicinity has a decent mix of English and Wampanoag (Native American) names.

The thing that can be frosting is when said people refuse to accept correction by the Native Bostonians on pronunciation.

We will not speak of Worcester, Gloucester, or Scituate. :-)
