Mary Ann loved people, was very kind and made life wonderful for all who knew her. She was a most loving and caring mother and had a great love of her Catholic faith.

Mary and Gerald were unable to attend mass after Covid, due to their aged years, but viewed the mass on television every Sunday morning.
