Mothers side:
Narrow ear canals, often leading to profound deafness in infancy and early childhood (not autism related- my mum had it and is as NT as they come, mine was cleared up with gromits when I was 3)
Longevity- my great uncles and aunts lived into their 90s. My grandfather died age 86 despite being a heavy smoker who had a lung removed during the second world war due to tuberculosis. Without antibiotics.
Intelligence- my mum got through a degree in law no problem, one of my uncles is a mathematician who helped design the maths curriculum taught in Scottish schools (Scottish Primary Maths Guide course). It's difficult to gauge for many of the older/dead ones as they didn't have much opportunity to get a good education. My uncle who's a mathematician was the first to go to university, and my mum went as a mature student as she had to go straight from school to work due to financial constraints. Henry Bell, the inventor of the steamship, is one of the earliest of my ancestors that I've been able to trace (although he may have had some sort of spectrum disorder if the descriptions of him made by his contemporaries are anything to go by, see http://www.electricscotland.com/history ... _henry.htm)
Creativity: Several of my living relatives are talented artists, some show great innovation in their professional work as well.
Dyslexia, Aspergers, ADD and other things at the mild end of the spectrum- My brother is dyslexic, 1 cousin DXed with AS, another cousin DXed with ADD. None of my older living family members have been assessed, but of the ones I know, 2 uncles, 1 aunt and 2 other cousins could easily be DXed. 4 females 3 males in total- I think the gender ratio is about 50:50, if the oral history regarding my recent ancestors and other dead family members is anything to go by. The females tend to be very eccentric (although some have had a nasty streak), but the males tend to be either very, very quiet and kind or exceptionally nasty.
Sociopathy- some of the treatment some members of my family have recieved at the hands of other family members is too awful to relate here. Some of the males who are suspected of being on the spectrum get frustrated and just can't control their tempers, and it's always their wives and children who suffer. Some of the (NT and possible spectrum) women are/were like this as well, although they tend to be psychologically rather than physically violent to their husbands. Their children recieve both forms of abuse from them.
A certain "look": We have old photographs going back over 100 years, and many of the people in them look practically identical to family members alive today, far more than you'd expect (no, there's not been any inbreeding). My great uncle, for example, looks so like my brother it's unreal.
Fathers side
I don't know so much about his relations as I haven't seen him for years.
Alcoholism: His mother and several of his male relatives.
Intelligence: He is smart inasmuch as he's good at rote learning. No imagination whatsoever. His sisters became doctors and I think some of his other family members pursued medical or academic carreers.
Autistic disorders: He has a lot of the traits associated with the AS, as does his brother and possibly one of his sisters. Don't know about the rest of his family.
