John M. Trainor, of North Grafton, formerly of Worcester, passed away on Wednesday, April 11, 2018, at the Rose Monahan Hospice Residence, surrounded by his loving family, just three days before his eighty-sixth birthday. His loving wife of forty-three years, M. Barbara (Farley) Trainor, predeceased him in 2003. John is survived by his three sons, John M. Trainor, II and his wife Kristine of Worcester, Charles F. Trainor and his wife Kathleen of Sutton, and Lawrence E. Trainor and his fiancé Sandra Gordon of North Grafton; a brother, Eugene Trainor of Boxborough; eight grandchildren; a great grandson; nieces and nephews. John was born in Batavia, New York, son of the late, Eugene F. and Ruth E. (Messinger) Trainor. Moving to Worcester as a young child, the city has been his hometown, and he lived here for many years, before moving to North Grafton two years ago. He served his nation proudly in the United States Army. He graduated from Saint John’s High School and earned a Bachelor’s Degree in Business Administration from the College of The Holy Cross. He furthered his education at Boston College where he earned a Master’s Degree in Social Work. He worked as a Social Worker for many years with the Department of Social Services, before retiring in 1989. His love of social work started while working with his mother Ruth at Friendly House. He had been a member of Our Lady of Lourdes Church in Worcester, and served as a Eucharistic Minister there for many years. He was a former member of the Knights of Columbus and enjoyed fishing, reading, his time at the lake and bee keeping. His love of the outdoors can be traced back to when he and his brother became the first two members of the Nature Training Center in West Boylston.
