Mary Lois York Knerr died at the University of Pennsylvania Hospital, surrounded by her family, on Saturday February 4, 2017.  She will be deeply missed by all who loved her.  She was born in Sugar Grove, PA, on April 3, 1926, one of ten children and the daughter of Ethel Walter York and Earl R. York.  She married Theodore "Ted" Knerr on April 25, 1947.  She graduated from Sugar Grove High School and later from Penn State University with a degree in Home Economics.  She taught for many years at Northwestern Lehigh High School in New Tripoli, PA.

She was a vibrant woman who had a deep love for her family, teaching, Penn State football, and travel.  She opened her home to many foreign exchange students and maintained a lifelong relationship with them.  She was an amazing woman, and in many ways ahead of her time- showing great strength in the face of any challenge, while showing great love and tenderness to all who knew her.

In addition to her parents, she is preceded in death by her loving husband, Ted, and brothers Walt, Hap, Ralph, Bill, Bobby, and sisters Vivian, Florence, and May.

Survivors: She is survived by son Robert Knerr of Cape May, NJ, daughters Barbara Mantz and husband Barry of New Tripoli, Marlene "Myke" Atwater and husband Pete King of Valparaiso, FL, and Kelly DeYoreo and husband Jim of Clayton, CA, as well as sister Arlene and husband Morton Williams of Sugar Grove.  She had eight grandchildren: Scott, Laura, Katie, Casey, Ashley, Maria, Sarah & Patrick, and four great-grandchildren:  Anna Rose, Jack, Jordan and Isla.
