Diane Jean Stewart

Diane Jean Stewart passed away peacefully on May 11, 2026, surrounded by love. Her passing leaves an immeasurable void in the hearts of those who knew and loved her. Diane was a woman of grace, empathy, wisdom, and quiet strength whose beautiful presence touched countless lives.

Born and raised in San Francisco, California, Diane grew up with a deep love for family and community. She graduated from Mercy High School in 1958 and later attended the College of San Mateo. Her kindness, compassion, perseverance, and devotion to famiily were evident in everything she did.

Diane was preceded in death by her beloved husband, Robert Stewart, and by her parents, Delia (Cinalli) Peters and Henry Peters.

Together with her husband, Diane raised her family in Almaden Valley in San Jose, creating a home filled with love, warmth, and lasting memories. In 1990, she relocated with her husband and children to Rocklin, California, where she continued building friendships and creating a life centered around the people she loved most.

Diane found joy in life’s simple pleasures and remained a lifelong, devoted fan of the San Francisco Giants and the San Francisco 49ers. Growing up in San Francisco, she carried her love for her hometown teams throughout her life, cheering them on faithfully through every season and celebrating their victories as cherished family traditions.

Diane cherished being a mother and grandmother. She leaves behind her daughter, Laurie Stewart; son, Mark Stewart (Joey); and her cherished granddaughter, Merielle, whom she loved and adored beyond measure. Her family was her greatest joy and proudest accomplishment.

Diane will be remembered for her gentle spirit, her wisdom, her empathy for others, and her ability to make people feel loved and cared for. Her presence brought comfort and light, and her memory will live on in the hearts of all who knew her.

A memorial celebration of Diane’s life will be announced at a later date. In lieu of flowers, a  donation to Placer County SPCA in Diane’s memory would be greatly appreciated.
