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. Three were criminal. Eight kept houses of ill fame. These people have married into other families, generally of about the same type, so that we now have on record and charted eleven hundred and forty-six individuals. Of this large group, we have discovered that two hundred and sixty-two were feeble-minded, while one hundred and ninety-seven are considered normal, the remaining five hundred and eighty-one being still undetermined. (“Undetermined,” as here employed, often means not that we knew nothing about the person, but that we could not decide. They are people we can scarcely recognize as normal; frequently they are not what we could call good members of society. But it is very difficult to decide without more facts whether the condition that we find or that we learn about, as in the case of older generations, is or was really one of true feeble-mindedness.) In 1803, Martin Kallikak Jr., otherwise known as the “Old Horror,” married Rhoda Zabeth, a normal woman. (See Chart II.) They had ten children, of whom one died in infancy and another died at birth with the mother. Of those who lived, the oldest was Millard, the direct ancestor of our Deborah. He married Althea Haight, and they had fifteen children, of whom more later.
