18 The Kallikak Family
When Martin Sr., of the good family, was a boy of fifteen, his father died, leaving him without parental care or oversight. Just before attaining his majority, the young man joined one of the numerous military companies that were formed to protect the country at the beginning of the Revolution. At one of the taverns frequented by the militia he met a feeble-minded girl by whom he became the father of a feeble-minded son. This child was given, by its mother, the name of the father in full, and thus has been handed down to posterity the father's name and the mother's mental capacity.
This illegitimate boy was Martin Kallikak, Jr., the great-great-grandfather of our Deborah, and from him have come four hundred and eighty descendants. One hundred and forty-three of these, we have conclusive proof, were or are feeble-minded, while only forty-six have been found normal. The rest are unknown or doubtful.
Among these four hundred and eighty descendants, thirty-six have been illegitimate.
There have been thirty-three sexually immoral persons, mostly prostitutes.
There have been twenty-four confirmed alcoholics.
There have been three epileptics.
Eighty-two died in infancy.
