Smith speaks of a legal case in which a girl, eleven years old, being safely delivered of a living child, charged her uncle with rape.

Allen speaks of a girl who became pregnant at twelve years and nine months, and was delivered of a healthy, 9-pound boy before the physician's arrival; the placenta came away afterward, and the mother made a speedy recovery.

She was thought to have had "dropsy of the abdomen," as the parents had lost a girl of about the same age who was tapped for ascites.

The father of the child was a boy only fourteen years of age.
Marvelous to relate, there are on record several cases of twins being born to a child mother.

Kay reports a case of twins in a girl of thirteen; Montgomery, at fourteen; and Meigs reports the case of a young girl, of Spanish blood, at Maracaibo, who gave birth to a child before she was twelve and to twins before reaching fourteen years.
In the older works, the following authors have reported cases of pregnancy before the appearance of menstruation: Ballonius, Vogel, Morgagni, the anatomist of the kidney, Schenck, Bartholinus, Bierling, Zacchias, Charleton, Mauriceau, Ephemerides, and Fabricius Hildanus.
In some cases this precocity seems to be hereditary, being transmitted from mother to daughter, bringing about an almost incredible state of affairs, in which a girl is a grandmother about the ordinary age of maternity.
