History's youngest mother (true)

In 1939, a man from a small village in the Andes mountains carried his five-year-old daughter Lina into a hospital in the town of Pisco, Peru. He indicated to the doctors there that the shamans in his village had been unable to cure the large tumor that was developing in her abdomen. Upon examination, the doctors learned that the swelling was not actually a tumor.

Dr. Gérado Lozada was told by Lina's father that she had been having regular periods since age three, but they had stopped about 7 1/2 months prior to the visit. He listened to the young girl's abdomen with a stethoscope, and heart a tiny second heartbeat. An X-Ray was also performed, after which there could be no doubt… to the doctors' astonishment, five-year-old Lina Medina was about seven months pregnant.

Soon she was transferred to a hospital in the city of Lima, where specialists confirmed the pregnancy. Lina's father was arrested on suspicion of incest, but due to lack of evidence, he was released. On Mother's Day in 1939, when Lina was just under 5 years and 8 months old, her baby was delivered by cesarean section. It was a healthy 6 pound baby boy, and was named Gerardo after the doctor who originally diagnosed Lina's pregnancy, Dr. Gérado Lozada.
