Janice Venette Mantle Harrison, age 90, of Slidell, Louisiana, passed away peacefully at her home in Pearl River on September 16, 2025. She was born on February 4, 1935, in St. Louis, Missouri.

She is survived by her sister, Merilyn Wagmiller; her son William and grandson Tyler; her son Thomas and his wife Ruchille with their sons James and Jacob; grandson Andrew Marquez and his wife Elena with their children Graham and Corinne; granddaughter Carley Ballou and her husband Nick with their daughter Cecelia Venette; and stepdaughter Susan Harwood and her husband Chris. She is also survived by many nieces and nephews. She was preceded in death by her beloved husband of 57 years, James Dawson Harrison, and her daughter, Nancy Harrison Barron.

Jan graduated from Drury College, where she was a proud member of Alpha Phi sorority, and later earned her master's degree from The Ohio State University. Jan dedicated her career to education as an English teacher and later as a librarian, and she continued to cherish connections with her colleagues through monthly retired teachers' lunches. She was a founding member of Northminster Presbyterian Church, where she served faithfully as an elder for many years. She also helped establish and run the church's Montessori school, reflecting her lifelong passion for teaching and nurturing young minds. Her faith and friendships at Northminster were central to her life, and she remained deeply engaged with her church community through groups, fellowship, and service. Jan was an active member of the League of Women Voters, where she held multiple leadership roles and encouraged civic engagement. She was a lifelong reader and was devoted to two book clubs—one through her public library and another with close friends—that met faithfully each month. Beyond her professional and community commitments, Jan shared a love of adventure with her husband, James. Together they spent many joyful winters skiing at Winter Park, Colorado, enjoyed fishing trips to Canada with their son Bill and grandson Andrew, traveled the world on numerous cruises, and delighted in swimming, a pastime she cherished throughout her life. These experiences filled their lives with laughter, exploration, and lasting memories.

In lieu of flowers, donations to the League of Women Voters, a nonpartisan organization dedicated to empowering voters, would be appreciated. www.lwv.org
