He was a physician in the Civil War in Co. D, the 36th Arkansas infantry. He was sent home due to a shortage of doctors from Polk to Stone Co AR.

After the birth of his son William "Dick", Thomas and Delilah moved from TN to AR. Thomas' brothers, Dr. George Washington Jones and Dr. John Joseph Jones were already living in Conway Co AR. Thomas moved from Conway Co AR to Brock Creek, AR.

Thomas and Delilah hid their gold in several places for fear of Jay Hawkers stealing it. Jay Hawkers came to their house one night and put hot coals to Thomas' feet to make him tell where the gold was. He gave them some and they left. They returned for more. When they returned, Delilah was cooking bread on the Dutch oven and was preparing supper. The Jay Hawkers kicked over the oven. Thomas gave them more gold and they left. The third time they came, they took Thomas down the road to kill him. The leader asked the others if he was Dr. Jones and they said "yes". The leader told them if they harmed Dr. Jones, he would shoot the last one of them. The men wore masks and Thomas recognized the leader before he said what he did. After this, Thomas hid in a cave and issued medicine from there. Delilah took him food at night and brought out medicine for the people. She would sometimes send a boy named Brock. Before going tot he cave, Delilah would lay her head on the ground and listen for horses hoofs. She was not to go thru the dark to the cave and was afraid "only of a man".

After the war was over, Thomas bought all the land where Scotland, AR now stands. Three more children were born here: Andy, Thomas and Rosia. Their only transportation was a horse. Once on a trip to Stone Co AR, Thomas stopped on the way to stay with some people who only had blackberries to eat. They promised him that on his way back, they would have bear to eat. They kept that promise.

Thomas was a promoter of church and education. He would go miles to isolated places and meet with men from the mountains and Red River communities. The men carried guns, which stood by the door while they listened to Dr. Jones read the Bible and play the flute. The men sang along. He helped organize places of worship. He and Delilah were charter members of the First Baptist Church (Antioch) located then, above Scotland. He donated the land for the Methodist Church, which still stands in Scotland.

Thomas was a member of the school board for many years. In 1890, Thomas and Delilah donated some land south of the Methodist Church to be used for Scotland Academy. Children came from Van Buren, Conway and Pope counties to attend school. His home was open for boarding students, 3 to 4 at a time. There was always music in the home and Thomas made musical instruments. The house still stands in Scotland as well as the home of their son Ben, built in 1906.

Thomas decided to become a doctor after the death of his brother, George.
