On my mother's side, most definitely. They're all extroverted NT people who are into appearances, grand demonstrative emotions, family parties with dancing, laughing, shopping, and all the things that make me cringe. There's a heavy emphasis on beauty and poise and high heels. My grandmother was a fashion model in California in the 1950s.
Say no more.
My father's side was tiny and none of them are still alive. They were always much more like me. It stands to reason that I'm confident my father and his father, if not more of them, would have been identified on the spectrum.
