Mary R. Kemp, 91, of Lancaster, passed away Monday, January 27, 2020 at the Glen at Willow Valley. Born in Williamstown, PA, she was the daughter of the late William T. and Erma M. (Bond) Challenger. Mary enjoyed 64 years of marriage with her husband Dr. Robert M. Kemp before his death in 2017.

A graduate of Williamstown Catholic High School, Mary completed her RN studies at St. Joseph Hospital School of Nursing. She worked as a nurse, supporting her young family while her husband Bob completed medical school, and then worked beside him at his Willow Street practice.

Mary was a faithful parishioner of Historic St. Mary's Catholic Church, and she enjoyed volunteering at church activities. She also volunteered with the auxiliary of St. Joseph Hospital and served on the Board of Directors at Lancaster Catholic High School.

Mary's life was an example of patience, kindness and generosity. She was a selfless, loving and devoted wife, mother, grandmother and great-grandmother. She enjoyed a special bond with her brothers and sisters and was a loyal friend to many. Mary was a wonderful cook and loved hosting large gatherings where all were welcome. Her greatest joy came from making others feel loved and supported.

Ramirez (Miguel); six grandchildren: Andrew and Brian Notarianni, Sarah and Alexander Kemp, Ryan Ramirez (Kelsey) and Elizabeth Ramirez; her great-grandson Joseph Notarianni, and her siblings, John J. Challenger (Molly), Catherine Ahrens (Robert) and Helen O'Boyle.
