We celebrate the life of Joan (Hemstreet) Seville, born December 12th, 1941, who passed away on June 10th, 2026, in the presence of her children in Lincoln, Mass. She leaves behind a world made more beautiful by her art, her gardens, and her generous spirit—evident in the warmth and kindness she showed to friends and family alike. Known as MorMor to her beloved grandchildren, Joan was an artist, a gardener, a gourmet cook, and an advocate for community—a woman with a contagious smile who easily made friends wherever she visited or lived. Her spunk and positivity will be missed by all who knew her.

The oldest of four children, Joan grew up in Milton, Mass. She played basketball at Milton High School and, outside of school, was active as a Rainbow Girl. After graduation, she attended Katharine Gibbs Secretarial School. On one of her first jobs, at APT Associates, she met Alfred Seville at a business function and they were married in 1967. Having grown up as a beach girl, playing with her cousins at Humarock beach, she became a mountain girl when they married. Skiing in Zermatt on their honeymoon started years of adventures that included skiing at Glen Ellen, Vermont, where Al built a small cabin, as well as in Europe and Scandinavia.

After her children were born, Joan dedicated her time to raising them and creating a welcoming home for all. She loved hosting family gatherings, especially the Swedish Christmas Eve celebration, and her door was always open to neighbors and friends. As an avid gardener, she created beautiful gardens surrounding their home in Lincoln, Mass. She always had fresh flowers in the house, including magnificent African violets.

Joan discovered a love of art during high school and continued to develop her talents through the years, both attending and teaching classes throughout her community. The walls of her family's homes and multiple art shows are a testament to her talent and joy in capturing the beauty of the world—especially flowers—on canvas. Her grandchildren fondly remember art projects with her, and several of them seem to have inherited her artistic talent.

Joan was actively involved with Weston United Methodist Church over the past four decades, and we extend our gratitude to the church and its members for their support during the years she could no longer attend in person. Thank you also to the incredible staff at The Commons in Lincoln for their compassionate care and love over the last 11 years, especially through the later stages of Joan’s life.

Joan is survived by her children, Michelle Seville (Mike Basel) and Don Seville (Colleen Lannon); her grandchildren, Nic and Erik Lawrence and Finn and Caitlin Seville; her brothers, Edward Hemstreet (Alyce Hemstreet) and Lawrence Hemstreet (Fran Hemstreet); several cousins; and many nieces, nephews, grandnieces, and grandnephews. She was predeceased by her husband, Alfred R. Seville, and by her brother, Donald Hemstreet.

A Celebration of Life will be held on Sunday, June 28th at 2:00 pm at the Weston United Methodist Church, 377 North Ave (RT 20), Weston, MA, with a reception to follow. 

Flowers or donations in Joan's memory may be made to Weston United Methodist Church or Lincoln Parks and Rec Open Studio.

Arrangements have been entrusted to Dee Funeral Home & Cremation Service of Concord.
