Robert Ward Johnson was born on July 22, 1814, in
Scott County,
Kentucky, to
Benjamin and Matilda ( Williams) Johnson. His father had three brothers who were elected as U.S. Congressmen and the family was politically prominent in the state. His grandfather had acquired thousands of acres of land in the area at the end of the eighteenth century. The family were slaveholders. His siblings included a sister Juliette. His paternal uncles were
Richard Johnson, a United States Representative and Senator, and
vice president of the United States under
Martin Van Buren; and his brothers
James Johnson and
John Telemachus Johnson, older and younger, respectively, who were each elected as U.S. Representatives from Kentucky. In 1821 when Johnson was seven, his parents moved the family to
Arkansas Territory, where his father had been appointed as Superior Judge. At times, 200–300 boys attended the academy. The Choctaw students were at the school in the period prior to the
Indian Removal in the 1830s of the "
Five Civilized Tribes", but they were under pressure in the Southeast from encroaching settlers. His uncle kept the school going into the late 1830s, after some peoples had been forcibly relocated to
Indian Territory west of the Mississippi River. The young Johnson went on to study at
St. Joseph's College, an academy in
Bardstown, and graduated. After St. Joseph's, Johnson returned to Little Rock. He studied law as a legal apprentice and was admitted to the bar in 1835. He married Sarah Frances Smith in 1836. They had six children together; three survived to adulthood. Sarah died in 1862, during the
American Civil War. The next year, Johnson at the age of 49 married her younger sister, Laura. They had no children. ==Political career==
