William J. Moerchen, 91, of Swansea, IL, passed away peacefully surrounded by family on Monday, March 25, 2024. He was born on May 25, 1932, and throughout his remarkable life, he touched the hearts of many with his dedication, kindness, and zest for life.

He was a kind, compassionate and loving husband, father, grandfather, and friend.

Bill proudly served his country in the US Air Force, enlisting at the age of 18. As a member of the 159th Troop Carrier Wing, he displayed exemplary courage and was promoted as Airman First class to Corporal, earning the Air Force Commendation Medal for Military Merit for his outstanding service to the General.

A lifelong learner, Bill graduated from St. Teresa grade school and Cathedral High School in 1950, laying the foundation for his future successes. He was deeply involved in his community, particularly as a longstanding member of St. Teresa Parish. Bill had a strong devotion to his catholic faith. His contributions extended to various organizations, including the Rotary Club, Men’s Club, school board, choir, and perpetual adoration. Additionally, he was a valued member of the Loyal Order of the Moose and Elks.

In 1957, Bill married the love of his life, Marilyn Thouvenot, sharing 66 years of unwavering love and devotion. Together, they raised three children, Joseph, Mark, and Lisa, who were the pride and joy of his life. His dedication extended beyond family to his professional endeavors, as a professional land surveyor and member of the Illinois Professional Land Surveyors Association.  Bill was an owner at TWM engineering and Geospatial services, Thouvenot Wade and Moerchen, where he played a pivotal role in its growth from three employees to 130, spanning three states.

Beyond his professional accomplishments, Bill found joy in numerous hobbies. From hunting and fishing to photography and birdwatching, he embraced each moment with enthusiasm. He had a green thumb and enjoyed gardening. He took pride in his culinary skills, even winning the Rotary Club chili cook-off. An astute observer of the stock market, he cherished his time with friends in an investment club and coffee club.

Bill is preceded in death by his parents, Joseph and Mary Moerchen; his brother, Richard Moerchen; father-in-law and mother-in-law, Roland and Althea Thouvenot; and a sister-in-law, Audrey Johnson.

He is survived by his beloved wife, Marilyn; three children, Joseph (Jackie Lake), Mark, and Lisa (Michael Hillyer); four grandchildren, William Moerchen, Paul Moerchen, Rachael Hillyer, and Erika Hillyer; his sister, Betty Cerulli; a sister-in-law, Barbara Moerchen; a brother-in-law, Roland Thouvenot; and many dear nieces and nephews.

Marilyn and family, so very sorry to hear of Bill's passing. I remember you all as the wonderful neighbors, who lived 2 houses away, while I (Janee Lanter) was growing up. And, I remember babysitting for Joe, when he was just an infant. Allan remembers Bill's helpfulness in running copies for him on a couple of occasions. Al is also a land surveyor (now retired) here in Indiana. When Al offered payment, Bill laughed and said, "Just tell Elmer (Lanter) to buy me a beer." Good neighbors and friendship will never be forgotten. Al and Janee

I knew Bill as a neighbor, fellow Rotarian and more. Bill had a very calm and deliberate way about him, yet seldom that you had to ask him what his point was. Bill lives on in the many lives he touched and things he helped bring about. To Marilyn, Bill's children and loved ones, our condolences. All that made his life worthwhile now live on in you.

Bill has always been a mentor and friend to me since I joined TWM in 1994. He was an advisor to all of the surveyors and loved talking about Land Survey. Bill also loved eating and was always our Chief cook at the annual picnics. Steaks were cooked to perfection!! I am proud to have called him a friend and send my condolences to his family.
