My dad for sure!
Of course he was born in 1902 so by the time it started showing it was probably another 30 to 35 years before Dr. Asperger did his work, and another 50 after that before it became recognized as a diagnosis.
Some of what appears to be my aspie traits turn up a lot in the family, but perhaps not in enough of a cluster to be recognized as a diagnosis.
My branch of the family was separated from the rest of my dad's family so things there are very vague, nevertheless from the stories I hear, it is probably they were showing aspie traits.
As to my cousin, on my dad's side, He was always known for his quirkyness and it looks like he qualified.
My first son, (deceased) shows a lot of my traits and made his living as a computer geek. That and other things make him a likely case, however we were estranged slightly then completely shortly before I ever heard of aspergers. One key trait was that although he was quiet and well behaved he was a bully target and not doing well in school, except he excelled in all things computer. He was tested to see if he might have some learning oddity. The letter that came home stated ".... has tested in the 99.9th percentile, please have him see the gifted students counselor at once".
My second son shows traits as well, mostly noticed by his girlfriends and ex. Oddly enough he seems to have exceptional people skills, but he may be doing that primarily based on his definitely very high IQ. At the same time he seems to make some colossal mis-reads of people from time to time.
I've some nieces and grand nieces that seem to show signs, but I am not close enough to them to recognize them if I passed them on the street (but hey isn't that what prosopagnosia is all about, and I have a pretty good case of that) but the signs are there, unfortunately, some of them have other diagnoses which many aspies have recieved incorrectly before getting an AS diagnosis, (I am judging by what I have seen on some of the boards here).
When I was young I thought I was very different from dad, Now that I am 65 and looking back, I see that I am so very much like him, more than anyone else in the family, and the aspie things are the things that stand out the most.
