Robert Michael "Bob" McDonough, of Limington, died Monday at the age of 75. Bob was born in Boston on February 27, 1940, the towheaded only child of Helen and Michael McDonough. He graduated from Milton High School and Boston College, then joined the Navy, serving on the USS Norfolkas the Damage Control and Legal Officer on tours that took him to South America and Guantanamo, Cuba, during the Cuban Missile Crisis. His love of the water was unmistakable: in his bachelor days, he lived right on Commercial Wharf in Boston Harbor, and spent many happy hours sailing the Uisce Beathaaround Boston's waterways. An actuary, he worked for John Hancock Insurance, New England Mutual, and Unionmutual, which brought him to Maine with his wife Lois in 1972, and where he was part of the Pension department team. He retired in 1989 at the age of 49 -- after which time he refused to wear a suit or tie for any reason. A quiet nonconformist, Bob had a rich -- though understated -- sense of humor; many people remarked that they could never be really sure whether or not he was kidding. (He usually was!) He enjoyed his 25 years of retirement, managing their 130-acre farm, playing golf at Salmon Falls Country Club in Hollis, researching his family tree, rooting for the Patriots and Red Sox, and travelling to Ireland, where he had dual citizenship. He is survived by his wife Lois; his four daughters: Tara, Sheila, Meghan, and Kathleen; and three granddaughters: Siana, Amaya, and Lilli.The family would like to thank the hospice, “Life Choices”, and especially Bob’s care givers at Avita of Stroudwater.Funeral services will be held in his hometown of Milton, Massachusetts.

Thomas Funeral Home, 326 Granite Ave., Milton Thursday morning 9 to 10:30 followed by a Mass of Christian Burial at St. Mary of the Hills Church, Milton Thursday at 11.
