Bill (William) David Koehler, age 66, passed away on April 4, 2023. He was preceded in death by his mom, Ruth Webb, step-dad, Herb Webb, dad, William (Arlyle) Koehler, and sisters, Diane (Rick) Locke and Leisa (Jeff) Wilson. William is survived by his beloved children: Jason (Kelly) Cuellar, Caesar (Gabby) Cuellar, Mike (Mikel) Cuellar, William (Andrea) Koehler, Elizabeth (Tom) Weatherdon; and loving grandchildren: Tom, John, Evelyn, Robert, Liam (William), David, Max and Alex. He loved three things a lot in life and those are as follows: God as his Heavenly Father, his family, and riding his motorcycle with other members of the Vigilantes M/C. Bill was a proud grandfather and loved his grandkids immensely. He was very proud of the fact that people called him Preacher Bill. In the summer, you could find him in downtown St. Clair where he moved to live out the remainder of his golden years. He affectionately called the little town Mayberry. Bill would talk to anyone. As of six months ago he was walking 6 miles a day and bench pressing 345 pounds at 65 years old. Bill fought until the very end when not cancer but coronary heart disease took his life. He had a laugh and a voice that was unmistakable, and he will be greatly missed. A visitation will be held on Sunday, April 16, 2023 from 2:00 p.m. until 8:00 p.m. with a funeral service at 6:00 p.m. at Kaul Funeral Home, 28433 Jefferson Ave., St. Clair Shores.
