Mary held multiple titles throughout her life, but being a mother was by far her most cherished
until she was awarded the title of grandmother, affectionately known by her grandchildren as
“Noni”. As a mother, she was an active and passionate supporter attending all sports and
extracurricular activities and this compassion and dedication continued with her grandchildren.
Mary’s eclectic, explorative, outgoing, and fun nature was actively displayed throughout her life
from being an accomplished pianist, to a skilled and passionate horse rider, swimmer, tennis
player and pure love for all things outdoors especially spending time at the beach. Mary will be
remembered most for her cheerful, fun, affectionate, nurturing nature, opening her home, and
making everyone feel like family. She was easily loved and will be deeply missed by those lucky
enough to have known her.
