This is the history of two patients who have been found to be related, the great grandfather of the one was the brother of the grandmother of the other. The principal mating under D 7a is that of a +feeble-minded+ man married to an +epileptic+ woman, whose mother died in the insane asylum. They had six children, the first died when only a few months old, the next and the fourth were not bright and died young, the third is an epileptic, the fifth is feeble-minded and criminalistic and he is now at the State Home for Boys, the sixth is also feeble-minded and cared for at an industrial home for children. The mother and father, at one time inmates of the almshouse, are now supported by the town. Under D 7b the father, who died of spinal meningitis, was migrainous and had many epileptic relatives, the mother is neurotic. There were four children, the first an epileptic, the second died at 20 of spinal meningitis, the third is of a very nervous temperament, the last, a girl of 16, seems to be normal. [Sidenote: D 8] Both of the parents in this case are +feeble-minded+. The father was the black sheep of his family, his brothers are intelligent men, and for the most part good citizens; the mother, however, was the illegitimate child of a feeble-minded woman. There were seven children, one an epileptic, the others all feeble-minded with the exception of the sixth, who is now about 11 years old; she was taken from her home and put with a very good family; she shows the effect of the changed environment, and though not up to her grade in school, is only slightly backward. There is some doubt about the parentage of the child, and it is very probable that she is by a different father. Since the father's death the mother has had one illegitimate child; her children were taken away from her except the two oldest because of the immoral conditions in the home, and she now claims to be married to a feeble-minded man, who is the younger feeble-minded brother of her imbecile daughter's husband. [Sidenote: D 9] The central mating in this case is that of an +epileptic, alcoholic, sexually immoral+ man, married to a +neurotic and sexually immoral+ woman, who has many insane and feeble-minded relatives. They had in all ten children; two were epileptic, three, feeble-minded, one criminalistic and sexually immoral, the sixth is the only one who has a good reputation, the last was a stillbirth. The father and mother are no longer living together. [Sidenote: D 10] The case illustrated on this chart is of a +feeble-minded+ woman married to an +alcoholic+ man. The wife descended from an alcoholic father, who had several epileptic relatives. The husband also descended from an alcoholic father, and had an epileptic nephew. Of their nine children, the first three died young of scarlet fever, the fourth was epileptic, and the other five are feeble-minded. [Sidenote: D 11]
