from History of Saline and Lafayette Counties 1893:

JOHN D. MASTERSON, the well-known and very popular farmer who resides on section 1. township 50, range 24, Middleton Township, La Fayette County, Mo., was born in Marion County, this State, in the year 1836. His father was Hugh Masterson, a native of Kentucky, who removed to Missouri the year preceding his son's birth, and is said to be the first man that crossed the plains from Missouri, in the year 1849. The mother of our subject was Isabella (Hall) Masterson, a native of Kentucky, and a most estimable woman, greatly beloved by her family and friends. The paternal ancestor of John D., whose name also was John, was a soldier of the War of 1812, and was descended from Scotch-Irish ancestors.
The childhood, youth and younger manhood of John D. Masterson were somewhat uneventful, being passed quietly at home, attending the public schools, or working upon the farm, until grown up, when he took up regular agricultural pursuits. Now the tocsin of war sounded. Prompt to obey its call was our subject, who, in the year 1861, enlisted in Company C, Gordon's Regiment, Shelby's Brigade, Confederate States army. Among the first to enlist, he was among the last to stop fighting for a cause he believed to be just and right. After four years of faithful service, Mr. Masterson came to La Fayette County, and began farming, an occupation he has followed very successfully ever since. The farm of three hundred and twenty acres upon which he resides is all under cultivation and well improved.
Being domestic in his taste, it was not to be expected that Mr. Masterson would long remain a bachelor. In the choice of a wife he displayed exceptionally good taste and judgment, his life partner being Miss Sallie, daughter of R. H. Jones, a native of Kentucky. The children of this happy marriage are as follows: William, Linwood, John H., Zelda, Daisy and Elizabeth. A worthy and law-abiding citizen, Mr. Masterson takes, naturally, an interest in public affairs, and while it would not be proper to term him a politician, he is a Democrat, holding that that party best studies the interests of the country. In all the relations of life Mr. Masterson aims to be just and faithful, neglecting no known duty, and seeking to do to others as he would be done by. His neighbors hold him in esteem for his many sterling qualities of head and heart. The home of our subject is a happy one, filled with what is calculated to complete the sum of an ideal American home. Mr. Masterson is a member of Oriental Lodge, A. F. & A. M. Mrs. Masterson is a most worthy and acceptable member of the Christian Church, in the prosperity of which she feels an abiding and active concern.
