Why 1913? Did the TARDIS chose it? Is this a hint that she doesn't like Martha very much?
Well, there are worse times and places she could have chosen...
Algiers 1780? Jamaica 1800? Alabama 1958?
It was at least in an era and a location where Martha could survive without needing too much support in terms of culture, language, customs etc, would be in little immediate physical danger (low crime, no active wars), and wouldn't risk crossing paths with any close relatives...
