Bill was born on December 30, 1945, at home in Highland County, Ohio, to the late Paul Davidson and Mary Ruth Davidson. He was preceded in death by his twin brother, Robert “Bob” Davidson, and his older brother, Charles “Chuck” Davidson.
Bill was a devoted husband to his beloved wife, Ramona Davidson, and a proud and loving father and grandfather. He is survived by his daughter, Traci Davidson (Clinton Harpman), and his son, Eric Davidson (Jill Davidson). He was a cherished grandfather to Carter Davidson, Greyson Harpman, Spence Davidson, Brady Davidson, and Declan Harpman, all of whom brought him immense pride and joy.
A veteran of the National Guard, Bill carried a strong sense of duty throughout his life. He was a member of the Masons and a 32nd Degree Scottish Rite Mason, reflecting his commitment to community and fellowship.
Bill was the owner of Authorized Service, where he built a reputation for reliability, hard work, and integrity. He was someone you could always count on—no matter the time or situation. He lived his life as a steady, dependable presence, whose actions spoke louder than words.
Above all, Bill was the heart of his family. He was an amazing father, a proud grandfather, and a man who led by example—through kindness, hard work, and unwavering support for those he loved.
