Patricia “Pat” A. (Mansfield) Dennis, of Enfield, entered into the arms of the Lord on Thursday Oct. 15, 2015. Pat was the adopted daughter of John and Ethel Mansfield of Cornwall, CT and she considered it a privilege to grow up in the Cornwall/Canaan area. Pat was a proud member of the Class of 1956 at Housatonic Valley Regional High, and took great pride in being on the committee for the various class reunions. Pat left home after graduation, with her best friend, Paula, and headed for the Capitol city to secure a job. Her first job, at Hartford National Bank, is where she met her husband, John, and where she made many life-long friends. Later, as her family grew, she attended Asnuntuck Community College, and worked until her retirement at Alstom Power in Windsor. In retirement she became active with the Enfield Senior Center where she was president, for several years, of the Friends of the Enfield Senior Center. During this time she was the planner and group leader for many senior center trips to various parts of the country, and loved being with these people. Many became her followers and friends. Pat was also a founding member of Holy Family Parish, where over the years she taught CCD and co-directed the Women’s Guild. She remained an active member until the end. Pat was the beloved wife of John Dennis for 54 years. She considered her greatest blessing and treasure being mother to her daughter Colleen Mary (Dennis) Keating and her husband Tom, and her son John “Chuck” Dennis and his wife Thu. She loved them with an unending and unconditional love. Over the years she spent many hours with her beloved granddaughter, Valerie, and her darling grandson, Tyler.
