Kathleen Marie Siler, nee Tentschert, Baptized into the hope of Christ's Resurrection on Wednesday September 23, 2026, at the age of 78. Mother of James "Jamie" (Robin) Siler and Victoria Cunningham; sister of Debbie (Leonard) Riley, nee Tentschert, Patricia "Pat" (Gerald) Bernstein, nee O'Shea, Allen (Ann) Tentschert, and the late Judy (surviving Tony) Napoli, nee Mueller; blessed grandmother and great-grandmother, and treasured aunt and great-aunt to many.

Kathleen was born mid-May of 1948, bringing in the warmth of St. Louis summer to parents Allen H. and Adele, nee Steingrubey, Tentschert. Above all, Kathleen is remembered as a woman with a good heart who dearly loved her family. Her grandchildren and great-grandchildren were especially precious to her and brought her tremendous happiness and pride throughout her life.

Throughout her life, Kathleen wore many hats, but mainly spent her time as a homemaker who found fulfillment in caring for her family and home. When she wasn’t spending time with those she loved, she could often be found rooting for the St. Louis Cardinals, a favorite pastime she shared with so many fellow St. Louisans. We celebrate the positive memories her family holds in her heart, and rejoice that she is at peace with the Lord.

A visitation for Kathleen's friends and family to gather and share memories will be held on Tuesday September 29, 2026, from 11:00 AM until her funeral service at 4:30 PM at John L. Ziegenhein & Sons South County Chapel 4830 Lemay Ferry Road St. Louis, MO 63129.
