Lindbergh marries Anne Morrow, a writer and aviator, in a private ceremony. Their marriage becomes a significant part of their public image, with Anne accompanying Charles on many flights and expeditions.

The Lindberghs have six children: Charles Augustus Lindbergh Jr. (1930), Anne Spencer Lindbergh (1932), Jon Morrow Lindbergh (1932), Land Morrow Lindbergh (1937), Scott Lindbergh, and Reeve Lindbergh. The kidnapping and murder of their firstborn son deeply impacts their lives and family.

After his death, it was revealed that Lindbergh maintained three secret families in Europe. He fathered seven children with three different women in Germany and Switzerland, keeping these relationships hidden from his wife and the public. His German relationships included sisters named Brigitte Hesshaimer and Mariette Hesshaimer, and his Swiss relationship was with Valeska Christmann.

After Lindbergh's death, the existence of his European families was revealed, adding a complex layer to his legacy and raising questions about his personal life and moral character. His European children began to acknowledge their relationship with Lindbergh publicly decades after his death.
