Peggy Lou Mueller, Sherwood, aged 78, passed away on Wednesday, May 27, 2026 after a courageous battle with cancer. Peggy was born September 25, 1947 to Aubrey and Mildred (Klingler) Martin in Watonga, OK., and spent most of her early life in California.  On June 28, 1969 she was united in marriage to Joseph W. Mueller in Auburn, CA and moved to a dairy farm in Wisconsin.  Peggy enjoyed homemaking: cooking, baking, sewing and gardening.  She made many of her children’s clothes and her treats were always special. Peggy loved to help people and even home schooled some of her children. She valued education and in 1992 she received her bachelor’s degree, later her Masters, and eventually taught psychology.    Peggy also enjoyed traveling, especially cruises and reading a good book.  Most of all she loved spending time with her family, establishing a Sunday brunch and those times will always be treasured.
