The Farmer Funeral Home in Roseland, N.J., said Borino-Quinn died Wednesday after a long battle with liver cancer. Her husband, Luke Quinn Jr., had died in March.
A Roseland native who lived in Bordentown, Borino-Quinn had no acting experience when she was hired in 2000 to play Ginny Sacrimoni, the mafia wife with a weight problem. The character quickly became popular with fans and was featured in an October 2002 episode.
Borino-Quinn had attended the casting call mostly to support a childhood friend and was shocked when she was hired for the HBO show.
When she wasn't acting, Borino-Quinn worked at a New Brunswick law firm.
