p. 380	William McLouth Ely A distinguished lawyer in Nebraska is William McLouth Ely, who was born at Marion, New York, September 21, 1875, the son of William Brown and Mary Frances (Potter) Ely.  William Brown Ely, who was a leading
p. 381	physician, and at one time the president of Nebraska State Medical Society, was born in Connecticut, March 1842, and died at Ainsworth, Nebraska, June 23, 1921. Mary Frances (Potter) Ely was born at Marion, New York, July 6, 1844, and died at Ainsworth, November 7, 1926. Mr. Ely attended the public schools at Penfield, New York, and Marion Collegiate Institute, was graduated from the Ainsworth High School in 1892, and in 1900 received the Bachelor of Laws degree at the University of Nebraska, where he was a member of Alpha Tan Omega.  He has engaged in the practice of law at Ainsworth, since 1900, and has taken a prominent part in the political and civic affairs of his community. A Republican, Mr. Ely served as county attorney of Brown County, Nebraska, 1903-07, was county judge of Brown County in 1899, and in 1928 was defeated candidate for district judge.  He is a director in the National Bank of Ainsworth, is a member of the Ainsworth Commercial Club, and holds membership in the Country Club there.  He holds membership in the American Bar Association, the Nebraska State Bar Association, the Red Cross, Nebraskana Society, and the Young Men's Christian Association. During the late war he was chairman of the Four Minute Men, served as a member of the legal advisory board and the Home Guard, and was active as a member of the War Savings Committee. His fraternal organizations include the Royal Arch and Commandery bodies of the Masons, the Independent Order of Odd Fellows, and the Woodmen of the World. On June 7, 1905, Judge Ely was married at Ainsworth to Grace Maude Chesnut, who was born at Denver, Colorado, May 8, 1881. They have two children:  Samuel C., born January 9, 1910, who is a law student at the University of Nebraska where he holds membership in Alpha Sigma Phi; and Rebecca Frances, born January 30, 1923.  Residence: Ainsworth.
