Jacks early life before piratcy

Where do they say all of that?

man i want like the FULL biografy of jack. like hes real age, his childhood, his parents, does he have brothers or sisters, his first sex with a wench(lol) ok that was pervi of me.

how did he meet mr gibbs. omg so many questions.

I think that's what makes him such a cool character though. His background is such a mystery that it's easy for the audience to imagine what his background is like. I think the writers did this on purpose.

yea u know how they like to tease and make surprises

they want u to imagine everything u think the life of jack sparrow. then they probably surprise u something that u havent expected from jack.
