I pronounce the vowels in Mary, marry, and merry differently— like mail, marathon, and merit– but apparently that's not true in many places in the US. My regional accent is pretty mild, but I did grow up in a famously heavily accented area.
Yes MA, but closer to RI, which is fairly different in some ways. The closest famous example is Emeril Lagasse, who most people assume is from New York. One big factor is the short O pronunciation being a lot rounder. Coffee is cawfee, like it is closer to NYC.
