In the first chart Mr. Dugdale exhibits a detailed history of the illegitimate posterity of “Ada” throughout seven generations. The first legitimate consanguineous union in the family took place between the illegitimate son of “Ada” and a daughter of “Bell,” from which six children resulted. The branch is considered illegitimate, as far as “Ada” is concerned, so that Mr. Dugdale sets down each collateral branch as either legitimate or illegitimate, according to the legitimacy or illegitimacy of that child of the five sisters which stands at the head of the list. Now, glancing along the column of the third generation, or that exhibiting the six legitimate children of the illegitimate son of “Ada” and a legitimate daughter of “Bell,” we find their history to be as follows: The first, a male, lived to the age of seventy-five; was a man of bad character, though inclined at times to be industrious, and depended on out-door relief for the last twenty years of his life. The sisters and brothers of this man strongly resembled him in character, being all noted for their longevity, their propensity to steal, and their habitual licentiousness. They were, moreover, exceedingly indolent, with one exception, and were a constant burden on the township. It is unnecessary to trace out the history of these or of their descendants, except to present a few typical cases which will enable us to understand the conclusion arrived at by Mr. Dugdale. The first son of “Ada,” just mentioned, married a non-relative of bad repute, by whom he had nine children. This woman died of syphilis; and it is well to note at what an early period this poisonous strain showed itself in this the illegitimate branch of “Ada’s” descendants. These nine children surpassed their father, their uncles, and their aunts in criminal propensity. They were especially more violent, were frequently imprisoned for assault and battery, and, though no more licentious than their father, were especially addicted to licentiousness in its grosser forms. They inherited the constitutional disease of which their mother died, and with it the penalty of an early death, the oldest having died at the age of fifty-one and the youngest at twenty-four. It will be observed that they were not so constantly dependent on out-door relief as the generation immediately preceding them; this fact being attributable to the greater violence of their temper, which induced them to acquire by robbery and theft the means of livelihood, while the others preferred to beg. One aunt of these nine—viz., the second sister of their father and fourth from him in birth—never married, but had four children by a non-relative; and, for a purpose soon to be understood, we will compare their career with that of their nine cousins, who, it must be remembered, were born in wedlock. These four were illegitimate all the way back to their grandmother, “Ada”; and if there be any force in
