generally, in my experience players write their own history. Though, once (as DM) I asked the players if i could do it to try "something" (unknown to them, the thing i wanted to try was subtly sticking in something that related to the overall meta plot). In any case, they all said okay and i didn't get any hesitation so I went with it, and it worked out well. i did get some input from them with regards to "do you want the loner on the run type feel' the 'i cam e from a happy family' type feel, etc. so that the tone would be along the lines of what they are hoping for.
i think the key thing here is that a) i asked ahead of time and b) i didn't get any hesitation (aka no stammering or people thinking i was taking something away from them by doing this etc) and c) i did make the sure that the tone would match what they were comfortable with. and d) it wasn't an "always" this way, it was just to try something different than our usual game methods.
