RBaker52: I am researching a familial eye disease that runs in the Erbaugh ancestry. They descend from a Jacob Erbaugh (born 1797) who must have been a brother of Abraham 3 in your post. It is important for me to know if ANY blindness runs in the Erbaugh ancestry you mention. Any serious eye disease that caused the blindness may, in fact, be ADNIV, because it is a combination of all serious eye diseases (that cause blindness) rolled together, occurring simultaneously over time. ADNIV mimics other eye diseases, so it "looks like" retinitis pigmentosa, macular degeneration, glaucoma, uevitis, cataracts, etc. I can give you a great deal of information about the eye disease. Please email me at ADNIV [dot] awareness [at] G mail
