Catherine Regina Harrison

She was the beloved wife of the late James J. Harrison and a loving mother to Colleen Harrison and Scott Harrison (Margaret). Catherine was a cherished grandmother to Stéphane Ceccato (fiancée Sarah Francus), Adam Ceccato, Luca Ceccato, Justin Harrison, and Nicholas Antulov, each of whom brought her great pride and joy.

Catherine was the adored sister of Thomas McGowan and James McGowan, and the late Rita Wilkins, Michael McGowan and little brother Johnny.

A devoted family woman, Catherine found comfort and happiness in her daily routines. Her home was her pride and joy, and she took meticulous care of it. A true homebody, she loved the simple pleasures in life—watching Judge Judy, completing the daily newspaper puzzles, and keeping to the routines that brought her peace. A creature of habit, Catherine found beauty and contentment in life’s quiet moments.
