Kathleen Phyllis McKinnon

Kathleen Phyllis McKinnon, a lifelong resident of the Hough’s Neck neighborhood of Quincy, passed away peacefully comforted by the presence of her loving family on Thursday, September 18, 2025. She was 91.

She was born in Quincy to Katherine “Kitty” (Genter) and Michael Doherty. She graduated from Quincy High School. She met her husband to be, Robert McKinnon at a dance. The two made an undeniable connection and were soon after married, having 4 children. Becoming a mom, and eventually a grandmother meant everything to Kathleen. Her life centered around her family, and she thrived as a matriarch.

Her spare time was normally spent playing with her children, grandchildren and yes even a great grandchild. She was an avid traveler, from cruises, to road trips to tropical vacations, she visited many corners of the world and enjoyed every second. She often tried her luck at the casino or with a classic game of BINGO with friends.

Kathleen’s selfless devotion to her family, care and love for others will continue to shape the lives of all that were lucky enough to know and love her. She will be dearly missed.
