Katharine E. Sweeney

December 29, 1987 — November 9, 2022

Mt. Lebanon

Cherished daughter of Michael and Diane Sweeney. Devoted and much loved sister of Colin (Salta) and Anna. Treasured granddaughter of Lucy Sweeney. Beloved niece of Francis Simington, Carol McGoogan, Jack (Barb) McGoogan, Nancy Schmitt, Mike (Lori) McGoogan, Mary Ellen (Jim) Malcolm, Lisa (Malik) Soukehal, Richard (Marie) Sweeney, Paul Sweeney, and Kathleen (Don) Mente. Also survived and adored by many cousins and Mr. Quigley.
Kate was: a loving family member; a dependable, loyal friend; a dedicated and enthusiastic teacher; generous with her time and talents; deeply empathetic; kind, loving and nonjudgmental; smart, intuitive and inquisitive; relentlessly cheerful; bursting with wild creativity and artistry; a lover of books, knitting, trivia, mixology, and broadway; a collector of many things; quirky; an adventerous world traveler; fiercely independent and unapologetically sure of herself; playful and silly especially, but not exclusively, with children; fearless in many things.  Above all, Kate was loved.
