Lonna Parker (daughter of Frank E Parker) remembers a story Uncle Cookie (Wilfred P. Parker) told about the end of life of Wilfred C. Parker. A similar story was also told by Jacob Evans (son-in-law of W. C. Parker) to his children. Lonna Parker gathered the details that follow. On November 22, 1952 the University of Wisconsin football team tied Minnesota at Camp Randall in Madison. The Badgers were selected to represent the Big Ten in the Rose Bowl. On January 1, 1953 Wilfred C. Parker watched Wisconsin lose to USC 0-7 at the Rose Bowl in Pasadena. The family story goes that this loss proved to be too much for our dear Opa (as our grandfather was known), and he died four days later on January 5 back in Milwaukee.
