Mary L. Costello

1943 ∼ 2020

Mary L. Costello

Mary Louise (Proude) Costello, of Mashpee, MA and St. Augustine FL, beloved wife, mother, grandmother and friend, died Jan. 8 after a five-and-a-half-year battle with cancer. She was 76.

Affectionately known as Mary Lou to family and friends, she was passionate about golf, baking and life. She enjoyed every moment and loved a good joke, a party and just laughing with friends. She will be remembered for her feisty spirit and sense of humor.

Born in Quincy, Mass., Mary shared a joyful childhood with her siblings John, Billy, David and Linda and their parents, Howard and Elsie. She spent those early years on Kendall Street surrounded by love, many cats and a giant St. Bernard.

She graduated in 1961 from North Quincy High School, where she enjoyed many good times with her close girlfriends. After high school, Mary went on to work at the New England Telephone Co. in the Treasury Department. It’s there that she met Thomas Costello, and they married in 1964.

Mary and Tom started a family right away in Quincy, later moving to Brockton, where they raised their four children and lived for 20 years. Mary was a dedicated mother and home maker, skilled at many crafts, from sewing and knitting to crochet and ceramics. Always active, she loved to walk, compete in bowling leagues, and try her luck at Bingo. She could be seen regularly volunteering at charity events, manning the swim team concession stand, attending swim-team parent committee meetings, and on deck as a timer at swim meets, among other events.

She and Tom later moved to West Roxbury, where their son Tommy attended Roxbury Latin School. She never missed a wrestling match, lacrosse game or cross country meet and was always the parent cheering the loudest on the sidelines.

Mary worked for many years at Boston College in the Carroll School of Management. She absolutely loved B.C., her co-workers and professors she supported, and cherished the lifelong friendships she made there.

Mary had an ability to make everyone around her happy, and a gift for conversation and laughter. She could walk into a room and talk to anyone, and make even strangers feel at ease. Everyone wanted to be with her – not only for her genuine loving personality, but also for her fun-loving spirit. Those who knew her well would often say “she is one of the finest people I have ever known.”

Mary is survived by her husband Tom. They celebrated their 55th wedding anniversary in 2019. Their relationship was one of deep love and devotion, and they did nearly everything together. After retiring, Mary and Tom split their time between the South End of Boston, a home on the Cape, and a home in St. Augustine, Florida.

Mary loved her family and friends deeply and was always doing for others. She was unselfish and generous, and she put everyone else before herself even during her long illness. Her spirit will live forever in the hearts of her family and those who had the good fortune to know her.

In addition to her husband, Mary leaves her daughters, Susan Santonelli (husband Mike) of Winchester, Katie Friedel (husband Rick) of Scituate, Brenda Costello (husband Joel Wiginton) of Chevy Chase, Md., and a son, Tom of Portland, OR. She also leaves six grandchildren; Bridget and Maddy Nolan of Winchester, Emma and Evan Friedel of Scituate, Liliana Costello Wiginton of Chevy Chase, and Orion Costello of Portland.

She is also survived by her brothers, John Proude (wife Agnes) of Quincy, David Proude (wife Cheryl) of Taunton, and Billy Proude of South Carolina. She was predeceased by a sister, Linda. She also leaves brother-in laws, Edward Costello (wife Nancy) of New Bedford and Frank Costello (wife Beverly) of Watertown, as well as many nieces and nephews, and dear friends from around the world.

A funeral Mass will be celebrated at 10am on Monday, Jan. 20th at Christ the King Church, 5 Jobs Fishing Rd, Mashpee. Burial will follow at 11:30am in the Massachusetts National Cemetery in Bourne.
