Luci Baines Johnson Turpin
As the younger of President Johnson's two daughters, Luci Baines Johnson was just a teenager when her father took his oath. When she was 19, Luci—whose Secret Service code name was Venus—married Patrick Nugent in a high-profile Catholic wedding (a year before her older sister's marriage). The couple had four children before their divorce and annulment in 1979.

Luci is now married to Ian Turpin and lives in Austin, Texas. She is chairman of the board of LBJ Asset Management Partners and vice president of BusinesSuites, which both she and Ian own. In 2010, Luci was diagnosed with an autoimmune disorder called Guillain-Barré syndrome, which affects the nervous system. She received treatment at the Mayo Clinic before returning home to Austin.
