Isaac Daniel Inmon was born January 9 1851 in Weakley Co., TN, the son of Isaac and Nancy H. Faught Inmon. They family moved to Ozark, Mo in Christian Co before 1855 and on to Texas in 1865, settling in Pilot Point when he was about 14 years old. The article below was taken from the book "Fort Worth and the Texas Northwest". 
    Isaac Daniel Inmon. Achievements of a practical and substantial nature are credited to Isaac Daniel Inmon of Denton County, and perhaps the best of all has been the results of his work as a farm and ranch developer at his present attractive place eleven miles northwest of Krum. 
    Mr. Inmon was born in Giles County, TN (Weakly Co) a son of Isaac Inmon, who at the close of the Civil war accompanied the family to Denton County, TX, and followed his trade as a carpenter at Pilot Point until his death in 1873. The Inmons have been prominent and well known in this section of Texas for more than half a century. A brother of Isaac D. Inmon is Joseph M. Inmon of Denton, whose career is also sketched in this publication. 
    Isaac Daniel Inmon was a child when his parents moved to southwestern Missouri and located at the town of Ozark in Christian County. He acquired his early education there and was still only fourteen years of age when the family came to Texas. His people were not wealthy, and as soon as possible it devolved upon him to do for himself and he has absorbed most of his practical education without the aid of schools. 
    His brother and brother-in-law were blacksmiths at Pilot Point, and Isaac D. went to work in their shop at the age of fifteen and stayed there until he finished his trade. His father also did his carpenter work in the same shop. Mechanical ability is practically native to the Inmon family. After learning his trade I. D. Inmon went to Callahan County, TX and conducted a shop of his own for four years. He located there just before Christmas in 1889, and remained there four years. His next home was at Bloomfield in Cooke County, where he conducted a shop two years, and then bought a farm two miles west of the village. For two years he worked at his shop on the farm, and then gave his time and energies completely to the farm. 
    In November, 1913, Mr. Inmon moved to his present locality in Denton County, in the vicinity of Slidel. The land he bought was all pasture, and he and his family lived in tents until his first home could be built. The farm is a part of the Judge J. A. Carroll estate on the William Roebuck Survey. His residence and his barn mark some of the most generous and substantial improvements of the community. Two deep wells provide a copious supply of water for domestic and stock purposes. He has also constructed several miles of wire fencing and has brought almost three hundred acres under cultivation, chiefly to grain. His cattle are high grade Shorthorns, and he keeps a flock of Merino sheep partly to clean out the weeds from his pasture and also for the profit of their wool clip. Mr. Inmon has been working for himself more than half a century, and his material accumulations are represented by a ranch of more than eight hundred acres, regarded as one of the most desirable stock and general farms in Denton County.
     While living in Cooke County he served as trustee of the Breedlove School District, where his children were chiefly educated. He has no ambition in a political way. He supported the democratic party candidates for many years, casting his first vote for Horace Greeley in 1872 and the last for Grover Cleveland, but since then his allegiance has been with the Socialist party. 
    In the Bloomfield neighborhood of Cooke County, Mr. Inmon on January 16, 1879 married Miss Malinda Montgomery. Her father, Jeff C. Montgomery, came from Missouri to Texas and married Ann Jones, daughter of Reason Jones, one of the earliest settlers in the Bloomfield locality, and a man of exceptional prominence, whose lifework has been sketched elsewhere. Jeff Montgomery served as a Confederate soldier, and after the war located near Bloomfield, on part of the Jones headright, where he lived out his life. He was the father of three sons and four daughters: Mrs. Inmon, who was born on the Jones headright in 1857; Fannie, wife of Isom Mikiel, living in Cooke County; Robert Montgomery, of Durant, Oklahoma; Edward, of Wichita Falls; Alonzo, a farmer in the Breedlove Community; Lela, who died as Mrs. Earl Sipes; and Ada, wife of Emerson Parsons, living at Lois in Cooke County. 
    In their declining years Mr. and Mrs. Inmon have around and near them both children and grandchildren. Otis, their oldest child, a farmer near the homestead, married Pheobe Bates and has a daughter, Lorene. Homer, also on the home farm, married Eva Walker, and their children are Ray, Ethel and Earnest. The next in age is Miss Ethel, at home. James C. Inmon, a farmer in the home community, married Jessie South and has a son, J. C. Jr; Earl, the youngest, also active on the home ranch, married Myrtle Flowers and has a daughter, Nellie.
