Well, I have Asperger's, my oldest son has autism, my youngest son is non-autistic but gifted, their father is just anti-social and all by choice and non-autistic. My father has at very most very minor AS traits, mainly fixated on collecting sports cards. His father (my grandfather that I never met) possibly had Asperger's, on my father's father's side of the family, one of my father's cousins has a severely autistic teenage son and I have heard there are at least 3 other autistics as well on that side of the family. Not aware of any on my mother's side.
