This is wrong!
Russia's partial mobilization on the 26th understandably gave rise to considerable worry in Germany and Austria-Hungary. Only when Russia fully mobilized on the 29th did Germany responded.

Perhaps in our connected 21st century any such errors will be quickly picked up.
Did your great-grandfather or grandfather take part in the conflict? Did a great-grandmother become a nurse? Is there a death or several indicated in your family tree from this period? How relevant is it today tothe map of Europe and of the world?
