John Harty, son of Dennis and Dollie Harty, was here during the Mexican War and he came to Texas from Kentucky in 1837 and settled a grant of and there in 1839, situated about 16 miles ESE from Clarksville on waters of Anderson Creek and the survey began at the southwest corner of a survey made for his father Dennis Harty.
John had a wife and three children while in Red River County. Due to a terrible tragedy- a snake bit two of the children and while the mother was checking on them the baby fell in a wash tub and drowned- all in one day. The mother became despondent and soon died. John left Red River County, riding his horse to Cass County, to the village of Cusseta and built a two story log house. He traded that to Haney Floyd for 1400 acres of land that reached from John Russell's place to Dave Finley's place.
For the Mexican War, John chose a broken down horse to follow the authorities. A bad storm came up and they ran off and left him so he went home. For the Civil War he paid a man name Jacobs $15.00 a month and a horse and a saddle to go to war in his place. John made saddles for the Confederacy. He was very talented, made saddles, shoes, caskets and helped built the city of Jefferson. Uncle Horace said he was the 1st jurors that met under a tree, after coming to Cass County.
