In 1953, the Braves promoted him to the Jacksonville Braves, their Class-A affiliate in the South Atlantic League. Helped by Aaron's performance, the Braves won the league championship that year. Aaron led the league in runs (115), hits (208), doubles (36), RBI (125), total bases (338), and batting average (.362). He won the league's Most Valuable Player Award, and had such a dominant year that one sportswriter was prompted to say, "Henry Aaron led the league in everything except hotel accommodations." Aaron's time with the Braves did not come without problems. He was one of the first African Americans to play in the league. The 1950s were a period of racial segregation in parts of the United States, especially the southeastern portion of the country. When Aaron traveled around Jacksonville, Florida, and the surrounding areas, he was often separated from his team because of Jim Crow laws. In most circumstances, the team was responsible for arranging housing and meals for its players, but Aaron often had to make his own arrangements. The Braves' manager, Ben Geraghty, tried his best to help Aaron on and off the field. Former Braves minor league player and sportswriter Pat Jordan said, "Aaron gave [Geraghty] much of the credit for his own swift rise to stardom."
Aaron's first marriage was to Barbara Lucas in 1953. They had five children: Gary, Lary, Dorinda, Gaie and Hank Jr. He divorced Barbara in 1971, and married Billye Suber Williams on November 13, 1973. With his second wife, he had one child, Ceci.
