So after BTTF I -> one Marty in 1985.
In BTTF II... well actually after fixing the sports-almanac problem in 1955 they restored the original timeline.... so the Marty and Doc from 2015 wouldn't return to Hell Valley but the "right" 1985.
Just leave them there and follow the "almanac-destroying" Marty in 1955. He gets Docs letter from 1885 and travels to the wild west, preventing Doc from getting shot.
After that Marty leaves 1885 in the Delorean at the ravine..... and a couple of years later Doc leaves the wild west with the timetravel train.
Years are passing by until in 1955 the tombstone is not there anymore so the "almanac-Marty" then just leaves for 1985 because he thinks Doc is happy in the wild west. He leaves 1955.
Well and then after another 30 years when it is 1985 we will have Marty and Doc from the "almanac-fixed" 2015 returning.... Marty from 1885 returning and Doc with the timetravel-train arriving AND Marty from 1955 returning. Are these the 3 Martys? But hell we have 2 Docs too!

i think the previous posters are following the logic that if you intentionally travel through time with the goal of changing the timeline and succeed, this should erase the time travel altogether since there'd be no reason of changing the timeline;
-Doc wouldn't have any reason to take Marty to the futur since the children are in jail
-biff wouldn't need to steal the almanac and delorean if he were already rich
-doc and marty wouldnt need to go back to 1955 since the biffhoric timeline is avoided
-marty wouldnt need to travel to 1885 because there is no tombstom of doc dying
I don't subscribe to this theory but if I did; part I's trip to 1955 still happens because this was an unintentional time travel and not one with an inention to change the timeline.
Docs trip to 2015 at the end of part I still happens; it is an intentional time travel but not one to change the timeline. But he'd get there, look marty up and find everything is fine.
But yeah the original idea doesn't work because if you subscribe to the theory that martys trip to 1885 doesn't happen, you have to back track it to everying prior to part II. Plus Jules and Verne would not be born if not for marty in 1885; doc and clara still hook up without marty there but doc dies.
