The family had many adventures and happy times together while in California but returned to Rhode Island in 1965 to be closer to family. She was the Human Resources Administrator for Gulton Industries until her retirement.

She had only the highest praise for the staff and the facility. Mary will be reunited with her beloved husband in Rhode Island.
