Shields, Mary Theresa (Keane) on December 5, 2012,  of Quincy, formerly of Milton mother of three children Mary Paula, Diane and Dennis,  grandmother of Eric and Ian Shields, loving wife of the late Francis Bennet Shields lived a long and full life. She was always an advocate for God and caring for others. She loved life, dressed impeccably, celebrated her heritage, and loved a good Manhattan while discussing politics. Mostly she cared for those she loved focusing on them often to the exclusion of herself. She had several careers in her life time from the early years as a Legal Secretary to her true love as a real estate appraiser. She loved real estate , assessing value and doing what was right no matter how difficult. Mary Theresa was well respected in her profession, travelled frequently, and enjoyed her years of retirement. Her zest for life, sharp mind, quick wit, and sage advice (lectures to loved ones) will be sorely missed. Her courage in adversity and her perseverance have been rarely equaled in this world. A Mass of Christian Burial will be celebrated on Tuesday, December 11 at 11:00 in Sacred Heart Church, 386 Hancock St. Quincy.  Relatives and friends invited.  Visitation in the Dolan Funeral Home, 1140 Washington St. DORCHESTER LOWER MILLS, on Sunday 2-4 and Monday 4-8 PM.  Interment Center Cemetery, Hanover.  If desired memorial contributions in Mary Theresa’s memory may be made to the American Lung Association of New England, 460 Totten Pond, #400, Waltham, MA 02451.
