Minot was married in 1913 to Anna Marie Shaughnessy. They had five children, Ruth (born 1914), Wayland, Jr. (born 1915), Anna (born 1918), Elizabeth (born 1922), and Herbert (born 1925).[2] In the late 1920s, he lived in Cambridge, Massachusetts, and served as Parks Commissioner.[3] In 1930, Cambridge Mayor Richard M. Russell nominated Minot to serve as City Treasurer, but his nomination was rejected by the City Council.[4][5] Minot later became an investment counselor in Boston, Massachusetts.[6]
In January 1933, Minot was involved in a late night motor vehicle accident resulting in the death of one of his passengers. He crashed into a draw bridge of the Charles River Dam Bridge, and the vehicle burned. Minot was placed under arrest and charged with manslaughter.[7][8] Although a police officer testified that the smell of liquor was on Minot's breath, he did not believe Minot was under the influence, and Minot was found not guilty of manslaughter.[9][10][11]
