Thomas Jones joined a day-school at Pengam in 1881, the fees being paid by his father's recent promotion to a managerial post at A. Buchan & Co. It was here that he developed a love of reading and learning that was to stand him in good stead in his later career in the Civil Service where he became the confidant of four Prime Ministers.
