Mary will be remembered for her warm spirit, quick wit, and the effortless way she brought laughter into any room.

Whether through shared stories, laughter, or quiet moments together, she created a lasting legacy of love that will be carried on by all who knew her.

In addition to her family, Mary enjoyed many fond friendships while living at Minetto Senior Apartments and through her memberships in the local Red Hat Society, Ladies Auxiliary of Oswego Elks #271, and the Golden Ages. She was also a communicant of St. Mary’s and Our Lady of Perpetual Help Church.
