I suspect that my maternal grandfather may have had Aspergers. The rest of my family shows some autistic traits, but none of us have actually been diagnosed, as far as I know. My brother, though, was non-verbal until he was three -- rather than being concerned, they seem to have thought it was cute. The school thought he was mentally ret*d because he couldn't seem to learn to read until Mom went out and bought books on subjects that interested him -- planes and trains and construction. He's an engineer, now. My oldest sister spoke her own invented language until she was almost ten; I'm not sure what that's a symptom for, since I can't find much information about it. My second sister translated for both of them. I remember my mother consciously teaching me things that I now know I was supposed to pick up by observation and just didn't. I seem to remember Mom treating all of these things as if they were perfectly normal and we all ended up doing well in school and leading fairly normal lives, so whatever she and Dad did must have worked. We did all have a fairly strict upbringing when it came to formal behavior rules and what was expected of us.
