Sheila was born August 20, 1942 in Aurora, IL, the daughter of William and Dorothy (Desmond) Gaulke. She was in the first graduating class of Marian Central Catholic High School in Woodstock, Illinois. She continued her education at the former Shimer College in Mt. Carrol, Illinois where she met her future husband. Sheila married Arthur “Lee” Lassman on September 5, 1964 in Woodstock, Illinois.
In addition to raising their four children, Sheila was very generous in the Geneseo community with her time, talent and treasure. She was a longtime member of St. Malachy Church, a more than 30 year volunteer for the Hammond-Henry Ladies Auxiliary, volunteer for the John Deere Classic, coached youth softball and travel softball and she enjoyed crocheting blankets that were given to newborn babies. Sheila was a great supporter of her grandkids and Geneseo Sports teams. She loved sports and most enjoyed watching the Chicago Cubs, Bears and Bulls. When Patrick Mahomes emerged with the Kansas City Chiefs, she became one of their biggest fans. Most evident was the love she had for her family.
Sheila is survived by her children, Kurt (Brenda) Lassman, Geneseo, Kelley Lassman, New York, NY, Kristine (Daniel) Hitzhusen, Geneseo, Kent Lassman (Dana Damico) Alexandria, VA; grandchildren, Travis (Carlie) Lassman, Nicole Lassman (Omar Amaro), Scott (Dana) Hitzhusen, Bill Hitzhusen (Alli Hanson), and Esme, Desmond, Josephine, and Tobias Damico-Lassman; as well as numerous nieces and nephews. She was preceded in death by her parents; husband, Lee Lassman; sisters, Theresa McConville, and Julianna Mass.
The family wishes to extend a special thank you to the caregivers and staff at Allure of Geneseo for the compassion and love shown to Sheila.
