  • Dear Mary & Family. We have been friends since Sean was 3 years old and I was hired by Dad to work at Fendall. You had the most wonderful laugh and smile. 45 years have gone by too quickly and I know I will meet up for a re-union with you and John. I’ll plan on our last visit together in Quincy and we’ll chat again. Prayers and kisses.

  • Mary always had a smile and a wonderful way with her grandsons. Even when they were little, Mary would hold conversations with them in a grown up way. She loved having her children around her too and never complained about anything. I learned that her eldest Henry would get up every morning and make Nana her coffee, just the way she liked it. Then he would walk down the hall and deliver it to her. She was a wonderful lady and will be dearly missed by everyone who knew her.
