Yesterday, we asked a bunch of our favorite alternate history authors to list the biggest mistakes that they see other writers making in creating new historical timelines. One author who didn't get back to us by our deadline was Jo Walton, author of Farthing and several other great books. We just heard from her, and she raised an excellent point that nobody else had brought up yet:
The only thing that tends to drive me mad about alternate histories is when they have people born after the divergence point but they're the same people. So it's 1860 in a world where the Persians won at Marathon but there are Lincoln and Lee as if they're historically inevitable. Nobody would be the same! That's the whole point!
