I have a copy of the 1880 census record for my Gr-gr-grandfather. One of his son's is marked as 'Idiotic'. I just found this info... *" If you have discovered such an entry in a family you locate in the 1880 census, you will then want to find the corresponding entry in the Defective Schedules."* Does anyone know where I can locate a copy of the 1880 Defective Schedule...aka the 1880 3D schedule or 1880 Defective, Dependent and Delinquint Classes? Any help will be apprecitated.
