William Trisilla

William L. Trisilla, 86, passed away Friday, November 6, 2026 in Elgin, Illinois. He is survived by his wife of 36 years, Joanne Trisilla ( Dwyer) and his son Zachary (Alexis) Trisilla. Also survived by four sons from a previous marriage: Eric Trisilla, Craig Trisilla, Keith Trisilla, and Neil (Lynn) Trisilla. He is also survived by his sister Gloria Carter, grandsons, a granddaughter, and many nephews and nieces, as well as, friend Sue Colionne- Williams, and pets Blitz and Rookie.

Bill was predeceased by his parents Louis and Alice (Kazich) Trisilla, Sister Elaine and brother- in-law Wally Wasylowsky, and brother-in-law Paul Carter.

Bill was always quick to offer support, a joke, and a cup of coffee to all he met. He was a man of great faith and found his strength through prayer and his love for God. His faith also carried him through every season for every Chicago sports team, always praying for “this to be the year”! Football season always took precedence over every other activity–especially when the Chicago Bears or Notre Dame were playing.

William L. Trisilla will be missed by his family and friends–and as our Boy Bill would say, “I’m glad you got to meet me!”
