Clair W. Trost, Sr., 85, of Monongahela, Carroll Township, passed away peacefully surrounded by those he loved on Sunday, October 11, 2026, at his home.

He was born on December 14, 1940, in Pittsburgh, the son of the late Ruth Kohlmeyer Jones. Clair enjoyed hunting and had a passion for classic cars. He could fix and build anything and had the best sense of humor.

Surviving to cherish his memory is his daughter, Deborah (Chad) Williams of Monessen, grandchildren, Elizabeth (Zachary) Bittner, Alexis Trost, Jessica (Rafael Gutierrez) Angell, Benjamen (Amanda) Angell, Darick Trost, Megan Williams, Brooklyn Williams, and Elizabeth Williams; great-grandchildren, Isabella, Rafael Jr., Mateo, Jackson, Zoey, Evelyn, Santiago, and Wyatt; a nephew, Brian Dennis; and special sister in-laws, Sue Spencer and Karen Wheatley.
