The Donegal Athletic Club has selected two individuals to be added to the Memorial Monument wall located just outside the stadium at the Donegal Athletic Complex. The Donegal Memorial Monument was created to recognize people who have made significant contributions to the Donegal School District or the wider community. The newest honorees are the late Harold Billow and the late Michael Guinivan.

Billow served in the United States Army during World War II. He survived the Malmedy Massacare, during which 87 of his fellow servicemen were killed by German soldiers. Each year since returning home, Billow honored the 87 fallen soldiers on July 4 and Veterans Day by placing 87 American flags in his front yard in Mount Joy. For many years, Billow visited and spoke with Donegal High School students about his World War II experiences in order to increase appreciation of the sacrifices made by war veterans to preserve freedom.

Guinivan was an industrial arts teacher at Middletown Area High School for 34 years. Outside the classroom, he coached men's and women's swimming at Elizabethtown College, earning several Conference Coach of the Year awards. He also coached swimming at Willowood Swim Club in Elizabethtown and was influential in the Mount Joy Lions Swim Club, where he managed the pool in addition to coaching the swim team.

Guinivan also served on the Donegal School Board and was a member of the East Donegal Township Planning Commission. He volunteered with the American Red Cross and Meals on Wheels, and he was active with his church, Mary Mother of the Church, where he served on Parish Council and the Building and Grounds Committee. A member of the Mount Joy Lions Club, he served four terms as president and also club secretary.
