Claire A.

Seivert

Claire A. Seivert, 95, Rockford, passed away on Monday, November 9, 2026, surrounded by her family. She was born on June 19, 1931, the daughter of Joseph and Catherine (Donegan) Anderson. She married the love of her life, Raymond Seivert, at Nativity Church in El Monte CA on May 9, 1953. They were married for 58 years until his passing on February 3, 2012. Claire lived a life centered on faith, family, and caring for others.

Claire was a homemaker whose life’s work was found in the seven beautiful children that she and Ray had. She was also Ray’s biggest supporter while giving love and attention to the many friends and family around her. One of her greatest joys was babysitting her beautiful grandchildren, treasuring the time she spent with them and the closeness those moments brought. Throughout her life she was an avid reader who found deep comfort and quiet joy in books, often losing herself in stories that brought her peace and inspiration.

Her faith was also a guiding part of her life. Claire was an avid parishioner at Holy Family and gave generously of her time through volunteer work at the church and school where her children attended. Claire was a member of Women’s Guild, the Altar and Rosary Society, Eucharistic Minister, and participated in “The Happening”. For her children she was a room mother, a scout mom, and a hot lunch lady at school. She also spent time volunteering at St. Anne’s Senior Living Center. Her kindness, reliability, and caring spirit touched many lives and reflected the compassion with which she lived each day.

She is survived by her children, Christopher Seivert, Mark Seivert, Mary (John) Chlebek, and Joseph (Brooke) Seivert; her daughters-in-law, Debra Seivert and Valerie Seivert; and her numerous grandchildren and great-grandchildren. She is preceded in death by her parents; her husband, Raymond; her daughter, Jennifer; her sons, Michael and Richard Seivert; her granddaughter, Michel Bengtson; her daughter-in-law, Teri Seivert; and her sisters, Ceil Chatham and Tina Simon.
