Iris C. McFadden Staudenmaier, age 86, of O'Fallon, Ill. died at 7:41 pm, Wednesday, October 19, 2022, at Barnes Jewish Hospital in St. Louis. She was surrounded by her family.

Iris was born October 6, 1936, at Misericordia Hospital in Philadelphia, Penn. to Vincent J. McFadden and Florence M. Avellino Trenary and Robert N. Trenary. She married the late Colonel Herbert V. Staudenmaier June 17, 1961, at Travis AFB, Calif.

Iris is survived by her children Anthony (Lisa) Staudenmaier of Aviston, Elizabeth (Phil) Oakley of O'Fallon, Robert (Amy) Staudenmaier of Auburn, Kurt Staudenmaier of Shiloh, and Karen (Gary) Duren of Littleton, Colo.; and her grandchildren Jacob (Bethany) Staudenmaier, Nicholas (Jessica) Staudenmaier, Allyson Staudenmaier, Captain Colleen Staudenmaier, Denver Oakley, SPC Matthew Oakley, Jake Duren, and Taylor Duren.

In addition to her husband and her parents, Iris was preceded in death by a brother, Vincent McFadden.

Iris graduated from Philadelphia General Hospital Nursing School in Philadelphia, Penn. in 1958 and upon graduation went on to work in its Emergency/Receiving Ward. She then went to Brookside Hospital, El Cerrito, Calif. to the Surgical Ward prior to entering the Air Force.

Iris and Herb lived in many locations while in the Air Force. Their travels took them to Alaska, Texas, Virginia, New Jersey, South Dakota, California, England, and eventually settling in Illinois. During this time Iris was a member of the Illinois Trekkers Volksmarch Club and served as President for 2½ years and coordinated six volksmarches. She also volunteered at Scott AFB Thrift Shop.

Iris had a great love for her church and its family. She was committed to helping in any capacity. Her involvement with St. Nicholas Catholic Church included Parish Council, Education Committee, Community Life Committee, Eucharistic Minister, decorating the church at Christmas and Easter; and she helped initiate the Tree of Remembrance. She was the first woman to be named as a Parish Trustee and was a Recorder for the Parish School of Religion.

Iris enjoyed her grandchildren and instilled in them the love of nature, Classical music, and the joy of books. Iris loved her garden, reading, cooking, but above all, she loved the Christmas season. Decorating of her house started as early as August and went on for several weeks. "Mother Noel" would host ornament parties and Open Houses to share her love for the holiday with family and friends. In addition, she was a member of two groups of beautiful women; The O'Fallon Magnolias and Tuesday Ladies, who gathered for life celebrations and support.
