Let's see here, my mom came from a family which used to live in the fields then came to the city (i never saw my grandfather from that side ever =( died before i could remember him ), and if we check further back, who knows what we'll find, but thankfully with Quebec's civil and religious registries, it's possible to check your ancestry fairly easily (they even recently found out who was responsible for a congenital disease that afflicts most people born in the Saguenay region).
My dad is from France, he came with his family after the war, and decided he liked it there while the rest of his family went back to homeland. My grandfather served during WW2 as a commander of marine infantry and participated in some of the wars around french colonies. My Great grandfather was also in the military and served in WW1 as a general of subdivision (i reckon that's 3 star general, even De Gaulle had 2, not quite sure on the title, need to recheck the french army grades). My grandmother was from rather old noble family, the "De Gourset" (if i recall right), she's still alive, but she has Alzheimer and she's in her high 90s. <.< It's kind of worrying my uncle and dad, since her pension's almost run out >< .
That's about it i guess. =/ No one in my family ever had autistic traits or AS to a high degree. Which makes me think that either i'm somewhat of a mistake, or my AS is environnementally caused.
