Lynda Bird Johnson Robb
Lynda Johnson is the older of former President Lyndon B. Johnson's two daughters and was 19 when her father was sworn into office in 1963 after the assassination of John F. Kennedy. Lynda, whose Secret Service code name was Velvet, began a highly publicized relationship with actor George Hamilton in 1966. However, the couple soon went their separate ways, and Lynda married Marine Captain Charles S. Robb at the White House in 1967. The couple had three children.

It wasn't long after they were wed that Charles became the Governor of Virginia and also served two Senate terms. Lynda served as a contributing editor to Ladies Home Journal and got involved with the children's literacy organization Reading Is Fundamental. Today, she echoes her father's liberal politics as an outspoken supporter of universal healthcare and serves on the board of directors of the LBJ Foundation and the Lady Bird Johnson Wildflower Center.
