Marguerite Marie (Ohnemus) Sullivan, age 90, passed away at Bartholomew House, an assisted living facility in Bethesda, Maryland, on Dec. 22, 2017.

Marg was born and raised in Waltham, Mass., graduated from Waltham High School in 1945 and moved to Brunswick, Maine in 1967. She and her husband, Edmund C. Sullivan, raised two sons in Brunswick and were active members of the community for nearly 50 years.

After high school, Marg moved to Fort Myers, Florida, where she acted in numerous community theater productions. She later returned to the Boston area, where she worked for many years as an executive secretary at The Raytheon Company.

Marg was a passionate reader and loved the Brunswick and Topsham public libraries. She always did her crossword puzzles and Jumbles in pen, rarely needing a correction. She was an enthusiastic Bridge player. She was proud that she never missed one of her sons’ games or school events. And her children were proud of how well she could throw a baseball.

Marg was an obsessive Boston Red Sox fan. She regularly attended Spring Training games and loved Fenway Park, where she attended Game 7 of the 1975 World Series. She took her last breath wrapped in a Red Sox blanket.

One of nine children, she is survived by two sisters, Janet McAlpine of Framingham, Mass. and Eleanor Falzone of Waltham; and two brothers, Edward Ohnemus of Highland, California, and Bernard Ohnemus of Waltham. She is also survived by two sons, Kevin Sullivan of Washington, D.C., and Dr. Thomas Sullivan of Cincinnati, OH; as well as four grandchildren, Katherine and Thomas Sullivan of Washington, D.C., and Emily and Nathan Sullivan of Cincinnati, OH.

Ed Sullivan passed away in May 2015. Marg moved to Bartholomew House in November 2015, and was the house champion at trivia and word games.

Marg was devoted to her Catholic faith and particularly the Jesuits, who were a central pillar of her life and family. She was a longtime parishioner at St. Charles Borromeo Catholic Church in Brunswick. A memorial service in Brunswick will be scheduled for a later date.

In lieu of flowers, donations may be made in Marg’s name to Bartholomew House, 6904 River Road, Bethesda, Md., 20817.
