Elizabeth A. "Libby" Brennan, 34, of North Grafton, formerly of Worcester, passed away peacefully on Sunday, October 9, 2016, at Beaumont Skilled Nursing and Rehabilitation in Northbridge, after a long illness. Libby was born in Worcester and was the daughter of the late Honorable Martha A. (Scannell) Brennan. She graduated from Bancroft School in Worcester in 2001, and later received her bachelor's degree from Union College in Schenectady, NY in 2005. Libby continued her education by following in her parents' footsteps, earning a Juris Doctor degree in 2008 from Suffolk University Law School in Boston. After receiving her law degree, she worked as an attorney in the Worcester District Attorney's office for several years, and later worked with her father in private practice in Worcester, until her retirement due to illness. Libby enjoyed spending time at the beach, enjoying the company of family, friends and neighbors. Her closeness and devotion to her brother Joe, friends, family, and especially her late mother Martha, will be how she is forever remembered. Libby is survived by her father, Joseph F.
