Born in Lorain, to Irish immigrants in 1932, he graduated from Lorain St. Mary's High School in 1950, then worked his way through John Carroll University, graduating in 1955. On one fateful St. Patrick's Day, he met Mary O'Malley at a party. Lucky for him, he took notice of this blue-eyed beauty again at the same party the following St. Patrick's Day. Because it was a long distance relationship (she being an East-side girl and all) he had to drive from Lorain to a pay-phone in Cuyahoga County to call her. The two were married on July 19, 1958. Their family grew to include nine children. Mackin began working as an accountant in Lorain, Toledo and Cleveland. He attended law school at night, earning his Juris Doctor from Toledo University School of Law and John Marshall Law School in 1961. He joined the law firm of Jensen and Seeley in Avon Lake in 1964. He became a CPA that year. His 10 years working as Avon Law Director sparked his interest in municipal law and service. In 1988, he was elected Avon Lake Municipal Judge, becoming the only judge in Ohio history who was both a CPA and attorney. Mackin presided until 2006. When not working, Mackin taught countless boys and girls to play basketball as a coach for A.L. St. Joseph for 17 years. He served as CYO president, basketball tournament director and uniform manager. He was honored with the Vasiloff Award from Avon Lake Sports Hall of Fame. A Holy Spirit Catholic Church parishioner, Mackin was a member of the Father Ragan Council of the Knights of Columbus and the Mayo Society of Cleveland.
In addition to Mary, his wife of 56 years, he is survived by brothers, Dennis (Susan) and Michael (Carol); his children, Bridget (John) Schohl, Michael (Laura), Patrick, Terry (Andrea), Thomas (Allison), Maryhelen (Wayne) Chadwick, Brendan (Jennifer), Kate and Nora (John) Lally; and his grandchildren, Kevin (Caitlin), Allison, Colleen, Megan, Peter, Julie, Maura, Margaret, Aidan, Annie, John, Grace, Katie and Colin.
He was preceded in death by his parents, Anthony and Mary (nee Hackett) Mackin; and siblings, James, Patrick and Mary.
