Luci Baines Johnson is the younger daughter of U.S. President Lyndon Johnson and his wife, the former Claudia Alta Taylor. Her name was originally spelled "Lucy"; she informally changed the spelling in her teens. As her parents both had the initials LBJ, they named their two daughters to have these initials also. She was sixteen when U.S. President John F. Kennedy was assassinated and her father succeeded him. She heard of the assassination while she was in Spanish class and a girl came in and shouted it. Although her father was a member of the Christian Church Disciples of Christ, her mother was an Episcopalian, and she and her older sister, Lynda Bird, were raised as Episcopalians. Luci converted to Roman Catholicism at the age of eighteen, when she requested and received conditional baptism. Since Luci had been baptized with water and in the name of the Trinity when five months old by an Episcopal priest in Austin, Texas, her rebaptism caused protests from leading figures in the Episcopal Church, reaching the front pages. Roman Catholic teaching does not require converts who are already baptized to receive baptism a second time.
