M. J. Cleary married Bonnie B. Blanchard of Blanchardville—she was a granddaughter of Alvin Blanchard, who founded Blanchardville. They had at least three children. Their eldest daughter, Catherine Blanchard Cleary, was a pioneer woman in business, graduating from the
University of Wisconsin Law School and serving as the first female board member of
General Motors,
AT&T,
Kraft Foods, Northwestern Mutual, and
Kohler Co. After the
1952 United States presidential election, she challenged president-elect
Dwight D. Eisenhower to appoint a woman as
Treasurer of the United States. Eisenhower responded by appointing
Ivy Baker Priest, and then named Cleary as assistant treasurer. Cleary served less than a year in that role, however—she determined that the role of assistant treasurer was not needed and had the position abolished. She was subsequently appointed assistant to the
Secretary of the Treasury,
George M. Humphrey. She retired at the end of her business career as chairman, president, and C.E.O. of the
First Wisconsin Trust Co. ==References==
