it appears Northeast Savings was acquired by Shawmut, which was then acquired by Fleet, both transactions occurring in 1995.
Fleet was acquired by Bank of America in 2003.
I found a mortgage satisfaction at http://public.clerk.co.escambia.fl.us/xml_or_1b.asp?uinstr=1997385622 listing all of these as grantors, and the document describes them Fleet as a successor by merger (through the other entities) to Northeast Savings.
