He leaves his wife, Joyce Dunham McClay, of 48 years; his son Michael Edwin McClay, his daughter Marcia Ellen McClay Hall, son-in-law Jason Edward Hall, and grandsons, Mason Elijah and Wyatt Edward Hall, all of Lucasville.
Mark was born Jan. 28, 1938, the son of Floyd and Mildred Canter McClay.
Mark is survived by brother and their spouses, Roger (Faye) McClay and John (Shirley) McClay of Lucasville; sisters, Ruth (Walter) Phipps of Glouster and Mary McClay of Dayton.
Mark was preceded in death by his brother, Dean (Loretta) McClay of Arion.
Mark was a 1956 graduate of Valley High School. He was served in the U.S. Army Reserves from 19061 to 1967. He was employed Novamont Corp. Detroit Steel before retiring from the Atomic Plant in 1995 with 30 plus years of service as a Chemical Operator Supervisor in the 326 building. Mark was also a part-time farmer for many years.
Mark had many interests — boating and water skiing, antique car and tractor shows when he was younger, Ohio and Erie Canal history, genealogy and being on his computer as his health declined. Mark always had a camera available and loved taking pictures of his family, his pets and flowers. He lived for his grandchildren and was always giving them rides on his John Deer tractor. “Grandad” was at his happiest when he was spending time with his boys.
Mark was a member of Bear Creek United Methodist, and attended Howard United Methodist faithfully until his health prevented it.
Services to celebrate his life will be held at Boyer Funeral Home in Waverly, with visitation Monday 6 to 8 p.m., Tuesday at 1 p.m. with interment at Mound Cemetery in Piketon, Ohio, with Pastor Walt Arnold officiating.
