William Edward Theis

William Edward Theis “Bill” Age 68, of Lake Shannon, IL, formerly of Homer Glen, IL, passed away peacefully at his home on Tuesday, December 23, 2025, surrounded by his loving family and friends. Bill was born on June 29, 1957, in Chicago, IL, to Edward William and Mary (née Murphy) Theis. On August 19, 1988, he married Mary Jo Corcoran in Chicago, and together they shared over 37 years of marriage. Bill was self-employed as a general contractor for more than 40 years, taking great pride in his work and his strong dedication to his trade. He was also a member of St. Lawrence Catholic Church in South Wilmington. An avid outdoorsman, Bill enjoyed hunting and fishing and felt most at peace outdoors. He had a special affinity for Lake Shannon, where he spent all of his free time boating, fishing, and enjoying time with friends. Above all, he cherished time spent with his family and was known for his generosity, kind heart, and great sense of wit. He was especially known for his quick one-liners that could bring a smile or laugh to anyone around him. He is survived by his loving wife; daughters, Alyssa (Luka) Covic of Tinley Park, IL, and Cara Theis of Reddick, IL; and son, Edward (Karissa) Theis of Coal City, IL, a member of the Braidwood Fire Department. He is also survived by three grandchildren, Isabella (4), Vivienne (2), lovingly nicknamed “Chucky” by her papa, and Edward William (3 months), and was joyfully anticipating the arrival of an additional grandchild. Bill is also survived by his brothers-in-law, Patrick (Beverly) Corcoran, Michael (Linda) Corcoran, and Timothy (Mary Jo) Corcoran. Bill felt their loyalty and kindness made them true brothers, and he was honored to be a part of the Corcoran clan. He is also survived by many nieces and nephews. He was preceded in death by his parents; his stepfather, Richard Busch; his in-laws, Thomas and Carole Corcoran; and his two best friends, Michael Tunney his longtime foosball partner and lifelong friend, and Kyle Weis, his lil’ fishing buddy. Visitation will be held at R.W. Patterson Funeral Home & Crematory on Saturday, December 27, 2025, from 9:00 a.m. until 12:00 p.m. A procession will then proceed to St. Lawrence Catholic Church in South Wilmington, where a Mass of Christian Burial will begin at 1:00 p.m. Cremation rites will be accorded following services.
