Elizabeth Marie Thornton

It is with deep sorrow that we announce the passing of Elizabeth “Beth” Marie Thornton (née Hamilton), a beloved wife, mother, sister, aunt, and friend to many, who passed away quietly at her home in Barrington, IL, on December 27, 2025.

Beth was born in Elmira, NY, on June 23, 1965. She graduated from South Side High School in 1983 and earned her bachelor’s degree in accounting from St. Bonaventure University in 1987, where she met her husband, Michael Thornton II. They shared 40 wonderful years together. Beth enjoyed a 20-year career in the financial services industry, working as a project manager, before becoming a substitute teacher and a devoted stay-at-home mother.

Beth loved her Labrador dogs “Cappy” and “Clancy,” and enjoyed playing softball, reading, cooking, and hosting social gatherings. She was an avid fan of the Chicago Cubs and Bears. Family and her Catholic faith were Beth’s highest priorities. She had a deep love for Jesus and Blessed Mother Mary. She was a genuine, selfless, and loving soul who brought joy and laughter to all around her. Her warmth, generosity, and unwavering love will be missed by all who knew her.

Beth is survived by her beloved husband, Michael Thornton II; her loving son, Brendan Thornton; her sister, Jacqueline Jacobus; her father-in-law, Michael Thornton; her sister-in-law, Colleen (Michael) Irvin; and her brother-in-law, Patrick Thornton. She is also survived by many nieces, nephews, cousins, and dear friends. Beth was preceded in death by her parents, Thomas and Kathleen Hamilton (née Agan), and her brother-in-law, Brian Thornton.

A Mass of Christian Burial at St Francis de Sales in Lake Zurich and interment at St Michael the Archangel Catholic Cemetery in Palatine were held privately. 

In lieu of flowers, memorial donations may be made to St. Jude Children’s Research Hospital, 501 St. Jude Place, Memphis, Tennessee 38105.
