Back then, she was known by her maiden name, Martha-Ann Bomgardner. Born in Fort Knox, Ky., she and her family moved to Mount Holly (PA, Philly burb) after her father, an air traffic controller in the Air Force, was transferred to McGuire Air Force Base. Her mother also worked as a librarian on the base. Her parents now live in Mansfield.

Dead also asserts that Martha-Ann Bomgardner knew Mary Jo Kopechne fairly well, which indicates a certain amount of time together -- a good part of a day during a BBQ, for example.
All I know is that Judge Alito's mother said that Judge Alito's wife's family was friends with the Kopechne family and the Judge's wife knew Mary Jo.
I tried Googling around to find more, but there is a real suprising lack of information on Mary Jo and her family, outside of that one particular night.
