William P. Marqus

February 21, 1945 — February 13, 2022

Mr. William P. Marqus, of Watertown, formerly of Waltham, died Sunday, February 13, 2022 in Newton Wellesley Hospital. He was 76.

Bill was born on February 21, 1945, a son of the late Daniel and Doris (Mazochi) Marqus. He was raised in Waltham and graduated from Saint Charles High School. In 1964, he joined the United States Air Force and served honorably during the Vietnam War. After his service, he returned home in 1968 and started his courtship with Rosemarie Cannistraro. A year later, the two were married in Saint Charles Borromeo Church and settled in Waltham to start their family. They later moved to Watertown in 1977.

Bill Marqus was first and foremost a family man . . . and a coach— a lot of the time these were the same thing. This was evident by his unwavering appearances at his three grandsons' sporting events. Not only was he a coach, he was also a pretty good athlete in his day too. He was an all-state and all Catholic conference player in baseball, and a stand out basketball player at Saint Charles High School. Later in life, he enjoyed traveling and golf with his wife Rosemarie.

His wife and children were his life, and his grandchildren completed him; his last words were to make sure his grandkids knew how much he loved them.

Before his recent retirement, Bill worked for many years as the purchasing manager at QinetiQ North America, formerly, Foster-Miller, a defense engineering and technology firm in Waltham.

Bill is survived by his wife of 52 years, Rosemarie (Cannistraro) Marqus; his children, Jennifer Blakely and her husband, Edward of Waltham and Stephanie Stratton and her husband, Michael of Hingham; his three grandchildren, Brenden Blakely, Michael and Matthew Stratton; his siblings, Lorraine M. Bissett (Thomas) of Ohio, Daniel D. Marqus of Haverhill, Nancy R. Silva (late John) of Waltham, Albert J. 'Rocky' Marqus (late Patricia) of Waltham, Christopher Marqus of Sudbury and the late Thomas S. Marqus. He is also survived by nieces & nephews.

Family and friends will honor and remember Bill's life by gathering for calling hours in The Joyce Funeral Home, 245 Main Street (Rte. 20), Waltham on Thursday, February 17th from 4 to 8 p.m. and again at 9 a.m. on Friday morning before leaving in procession to Saint Luke's Church, 132 Lexington Street, Belmont where his Funeral Mass will be celebrated at 10 a.m. Burial with military honors will be on Tuesday, February 22nd in the Massachusetts National Cemetery, Bourne at 11:15 a.m.
