Okay. Well, I don't remember all of them. If you go through the two pages I gave you above there are fics that fit the 'Sam and Dean not knowing each other/not related/or grown up apart thing'. And I'm sure you'd find some you'd like there.
But here are some specifics where we see one of them first discover that supernatural things exist: "Checkmate ends the game" http://free-piratefic.livejournal.com/15761.html
"Pattern of Regret" http://saucyminxfix.livejournal.com/34368.html
"Taking the Fifth" http://archiveofourown.org/works/164210?view_adult=true
And here: http://www.delicious.com/redfoxrose/first-discover-supernatural These have the same premise of discovering the supernatural, except Sam and Dean grew up together.
